Texans are all about doing things in a big way and that includes saving and making money. One of the newest ways that residents across Texas are padding their wallets is by adding solar arrays to their homes. Most people know that you can save money with solar but aren’t aware that you can actually make money too.
The most popular trend in home design today is adding eco-friendly features. From full Net Zero homes to adding Energy Star appliances, homeowners are looking for ways to adopt a more eco-friendly lifestyle. Carbon footprint reduction has become a serious issue for people around the world.
One of the biggest roadblocks of adding solar to your home is the initial set up cost. Putting up solar panels and setting up a full battery and conversion system can be expensive. But, it’s worth the cost when you take part in a solar panels buyback scheme that will have the power companies paying you instead of you paying out to them.
We have put together a list of some of the ways that you can make money by adding solar to your home in Texas and around the country.
Lower Your Bills
The amount of money that you can save on your energy bills is largely dependent on the size of the solar array you choose to invest in. You can calculate how much solar power you need to run your home using an online app or talk to your provider about how many panels are right for your home.
Once you are set up you will start to see an immediate reduction in the cost to power your home. If you add a large enough array you can eliminate your energy bills altogether, putting money back in your pocket every month.
Raise Property Value
Your home is likely the largest financial investment that you will ever make. With the markets still recovering, it’s important to find ways to increase the value of your home. When you add solar to your home you can expect a 4% increase in your property value. That can be a big chunk for many homeowners and a great way to put money in the bank when it comes time to sell your home.
The only things in life that you can’t avoid are death and taxes. But, wouldn’t it be nice to make a better return during tax season? When you decide to go solar you can get a great tax break at the end of the year.
Up to 25% of your initial set up cost for home solar can be written off on your annual tax return. That’s a huge break for many families and allows you to invest in your solar package with confidence.
For those homeowners that end up collecting more solar energy than they need to power their homes, there are great benefits to signing up for a solar buyback program. This means that any power that you produce in excess of what you need can be sold back to be used by your local grid. This means that instead of sending money out to the energy companies, they will actually start paying you.
Money is a scarce resource. Don’t let monthly bills break your bank while there are numerous things you can do to minimize them. From adding attic insulation to insulating outlets, and installing programmable thermostats, you’ve countless options for reducing your utility bills. Check out the following tips for cutting down your monthly expenses affordably and more effectively. Plus, you will learn everything utility bills.
Incorporate Attic Insulation
Most of the energy people use at their homes goes toward heating or cooling. Research shows that most of this heat escapes to the attic. Most homes lack enough insulation up there to prevent heat from getting out.
Fiberglass insulation is extremely cheap and easy to install. In fact, you can quickly install them on your own. By effectively insulating your home, you could actually save up to 20 percent on your heating, as well as, cooling costs.
But if you can’t install attic insulation yourself, you can always get help online. There are numerous DIY tutorials that can help you through the process.
Install Programmable Thermostats
By installing a programmable thermostat, you’ll be able to save up to 10 percent on your utility bills. Set your unit’s temperature to drop during winter months and raise them during the summer months when you aren’t home. You can then program the unit to return to more comfortable temperatures right before you get home.
This will go a long way in reducing your energy bills and saving you substantial amounts of money. So, what are you still waiting for? Act fast! For more information, visit http://regionalenergy.ca.
Did you know that outlets and light switches can be a major source of air leaks? To prevent this, consider insulating them, particularly if they’re positioned on an outside wall. There are numerous types of specialized seals and insulation materials to choose from. And they’re specifically designed for outlets, as well as, switch plates, so you don’t need to worry about fire risks.
Upgrade to Low-Flow Showerheads
Older showerhead models generally put out 5 gallons of water per minute. On the other hand, low-flow showerheads put out a mere 1.5 gallons per minute and still allow you to enjoy forceful showers.
Even more, they’re easy to install. If you want something more efficient and affordable, then go for a low-flow showerhead. It will help conserve water and save substantial amounts of water every day.
Insulate Water Heaters
Did you know that insulating an older water heater could help you save up to 9 percent on water heating costs? Well, now you know. Insulating hot water heater jackets can prevent standby heat losses by 25 to 45 percent, allowing you to heat your water easily and more efficiently.
Why you should install a Smart HVAC Based System
The HVAC system accounts for more than half of the energy consumed in your home. That’s why a fault system is likely to increase the overall energy consumption in homes. However, with proper maintenance, you can lower these energy bills and still have comfort in your home. So, if you are planning to install an HVAC system in your home, keep reading. Among other things, you will learn about the benefits associated with installing smart based HVAC systems in your home.
Lowers Electricity Bills
Energy bills can be annoying, especially when they skyrocket. Even more, the global energy sector is strained. That’s why energy costs keep on increasing. But does this mean letting nature take its course? No. You can do something to lower these bills. In particular, switching to a smart based HVAC system can be your answer as far as reducing the energy bills in your home is concerned.
One of the biggest pluses of these smart HVAC systems is superior temperature variability. With a smart system, you have an HVAC that will give you the power to control tempt variability according to your needs. This means that users can cool and heat specific rooms effectively without moving from space top space. This saves time and gives you an easy time as you relax or go about your activities.
Another good thing about smart systems is that they give you access to smarter air. Remember, the quality of air is important when it comes to your health. And that’s where smart HVAC systems come in. With these systems, you have a solution that will reduce stuffiness as well as drafts. So, if these are the things that you are looking in an HVAC system, then go the smart way.
You Can Access Then Remotely
Smart technology gives users access to their systems from remote settings. This means that even if you are at work, you can still monitor the functioning of your system. Thus, it’s possible to set the temperature of your room from your workplace before reaching home. This not only reduces energy costs but also improves the overall efficiency.
Why Utility Bills Keep On Increasing
The dreaded energy bill is coming. It can be annoying. If you are unlucky, it will deflate your bank account. Of course, you can try several measures to control the energy budget. However, things may not work out, especially if you don’t pay close attention to your HVAC system. According to research, the HVAC is responsible for almost half of the energy costs in homes. Thus, if you need to bring these bills down, work on your HVAC system. It’s one of the best starting points. So, if you have been wondering why your monthly bills are steadily increasing, sit back. Here are the top reasons why your energy bills are not going down any time soon.
Age has a big say when it comes to the performance of your HVAC system. An old system tends to be less efficient. This means that it will work more to cool or heat any space. So, if your system has served you for years, expect the bills to continue going up. Similarly, a poorly maintained HVAC system tends to be inefficient. This means that it will consume more energy and pump up energy costs. However, don’t let these factors continue draining your money.
You can install a new HVAC system and drive the bills down. If you have the cash, consider going for a smart system. It’s efficient, convenient, and highly reliable. Also, consider maintaining your system on a regular basis. Consult with your heating and cooling contractor to schedule maintenance. According to experts, it’s advisable to do it twice per year.
The operating costs at a particular time can influence the amount you pay towards offsetting your energy bills. For instance, systems that were developed in the 1990s are less efficient than their modern counterparts. This can be attributed to the emergence of technological advancement. For instance, sensors have made these systems more smart and efficient. Thus, they consume less amount of energy, which plays a key role in bringing the energy bills down. Customers are advised to install the newest HVAC systems to bring the energy bills down.
Features also play a key role when it comes to cutting down energy costs. Modern systems come with sophisticated features that make them more efficient. For instance, the efficiency standards of modern equipment are on an upward trajectory. This means that modern systems have superior performance and efficiency than their older counterparts. Standard such as SEER, HSPF, as well as Annual Fuel Utilization is important in determining the efficiency of any system. Also, energy features like variable-speed fans, heat exchange technology, as well as variable speed based compressors can make your system more efficient.
The Locality’s Climate
Your local climate can also increase or lower the amount of money you pay towards energy bills. For instance, if you are located in an extremely cold setting, you will need more energy to heat the interiors. Consequently, your energy bills will be higher. On the other hand, those located in extremely hotter environments will spend more money to cool the interiors.
Also, the following additional factors play a key role when it comes to the energy bills of any home.
The thermostat and other control settings in your system
How the unit was installed
Maintenance levels of your system
The level of insulation in any home
Windows, doors, and other openings in your home.
Are you looking for quick ways to reduce your energy bills? Well, there are actually several measures you can undertake to minimize your electricity costs. According to http://www.regionalenergy.ca/alberta-natural-gas-company/, these measures include insulating outlets and switches, installing a programmable thermostat, insulating your water heater, and installing a low-flow showerhead. Doing this will go a long way in reducing your utility bills and saving you junks of money.
Numerous businesses nowadays maintain a supply chain globally. However, it is important to note that sourcing locally has numerous benefits to the company you are sourcing from as well as to you as a customer. Especially when it comes to sourcing energy, it is extremely beneficial for an individual to source it locally. For the individuals situated in the district of Dalane in Norway, Strom 365 with the website https://strøm365.no/stromleverandorer/dalane-energi/ is a local energy provider that supplies the municipalities of Bjerkreim, Lund, Sokndal, and Eigersund with their energy requirements.
There was a time when the consumers of energy had no choice but to use the power supplied to their homes by the government and the generalized power suppliers. The disadvantage many individuals faced due to this was the often shortage of energy and the fluctuating voltage that was a result of long power cables and ill-maintained power lines.
However, with the power supply being localized, it is now much more efficient to receive power from a company you can trust locally and can benefit from investing in the company as well.
When power is sourced from a local company, you are investing in a business that operates in your area. This means that you are helping improve the local economy and increasing its economic value as well. This also means that if there is more than one electrical company providing energy to your area, you will be promoting healthy competition between the companies and encouraging those companies to offer you competitive pricing.
We often fail to realize how much utilities can take away from our monthly income, and by being offered a good price for electricity which you consume in your household, you are, in turn, improving your monthly budget.
Another great benefit of sourcing from a private company is the fact that they might offer you to buy bulk energy from them or allow you to sign a contract according to the requirements of your household. Private companies often have various packages that they offer their clients, and these packages can include various amounts of electricity units that are based upon the history of consumption of the clients. These packages are often offered at a lower price than general power usage, and therefore if an individual is buying a package, they can benefit from it greatly.
However, it is important to know and predict your consumption requirements accurately as any extra power that you use apart from the package can cost you extra, or any units that go unused in your package might not be redeemable in the next cycle.
In conclusion, sourcing power from a private company can be beneficial for not only yourself but the power provider as well as the community you reside in. It is also a good idea to conduct adequate research before investing or drawing up contracts with any company as after a contract has been made; you will become bound to the contract. Knowing your requirements and knowing that you can trust the company you are buying from are two extremely important factors.
The solar energy market in the Philippines has been growing exponentially since 2018. In fact, the Philippines Board of Investments (BOI) had approved eight solar projects that year. The Solar Philippines Commercial Rooftop Projects Inc. oversaw all eight that were equivalent to $1.65 billion.
Even though, as of today, the solar power industry is still on the nascent stage, it is expected to gain massive support from the government moving forward.
Solar panels are becoming more accessible, for homeowners and businesses
The Philippines has hot and humid weather, which means households always require air conditioning. Thanks to the introduction of solar air conditioning, many homeowners can reduce their utility bills.
Some of the factors that will drive growth in the solar energy sector are the growing population, as well as the Philippines’ rapid economic development. When the Philippines succeeds in replacing diesel generators in most islands with solar energy, there will be a significant reduction in power outages.
A couple of years back, utility-scale solar was difficult to achieve due to the market’s regulatory changes. The price competition was too high, and only the largest capitalized developers could compete.
However, this is set to change because the new generation of renewable energy can now be distributed to private households. This ensures that each household can install a solar-powered air conditioner to reduce utility costs.
It is a huge win for homeowners and business people because they can now have more control over their energy consumption. Photovoltaic panels can be installed on the roofs of homes, apartment buildings, as well as business establishments.
The production cost of solar energy is expected to fall significantly between 2020 and 2025. As a result, solar will take first place for the cheapest source of energy in the Philippines.
The growth of photovoltaic systems in the Philippines will provide an immediate and more permanent solution to the country’s energy needs. The market is already registering a significant fall in the costs of photovoltaic cells.
Many households are jumping on this bandwagon and taking advantage of the affordability of solar power equipment. As a household in the Philippines, you greatly benefit from purchasing a solar air conditioner.
Residents are also adopting small-scale solar photovoltaic systems because the declined cost of PV technology makes financial sense.
3. Increased Grid Parity
The Philippines has a huge population, and without alternative sources of energy, the grid easily gets unstable. However, due to the introduction of renewable sources of energy like solar and wind, we can see a future where grid parity is guaranteed.
Since more private households can now depend on solar energy for their electricity needs, grid parity has steadily increased. Most households today use solar air conditioner to maintain a comfortable indoor environment. This is a highly cost-effective solution because solar energy is steadily getting cheaper than traditional energy sources.
Not to mention that the overall cost of electricity from the gird is decreasing as well. This can be attributed to the contribution of solar PV. Technological advancements are ensuring manufacturers can produce solar panels with higher solar PV module efficiency.
This means that you can install a solar hybrid air conditioner at home without worrying about the running cost.
There are plans underway to develop solar-storage microgrids in the Philippines. When this plan succeeds, solar energy will play a huge role in improving environmental health, human health, as well as people’s quality of life.
This will be a huge step towards achieving Philippine’s national climate change, greenhouse gas emissions reduction and renewable energy goals. Solar energy production allows the Philippines to reduce its reliance on fuel. The transition to low-carbon energy sources like wind and solar opens up economic development opportunities from a climate perspective.
It is essential to pair solar systems with solar-storage because this boosts the positive impact solar energy has on the economy.
During spring and summer months, the Philippines experiences great solar generation. However, without a storage solution for solar energy, this energy cannot be saved for later. Storage prices are still very high, not only in Asia as a whole but the world over. There are already hybrid solar storage projects in place, but they’re nothing close to bulk solar storage.
One thing is certain though, the prices keep coming down, and more and more solar farms are springing up. Soon enough, the Philippines will be in a position to store solar energy and eliminate over-reliance on fuels.
Harnessing solar energy has ensured that many households in the Philippines can make it through hot and humid days. Solar air conditioners allow homeowners to achieve a comfortable indoor environment without digging too deep into their pockets. These latest trends show that things are only getting better. We can see a future where solar energy is the main source of electricity in the Philippines.
Biomass gasification involves burning of biomass in a limited supply of air to give a combustible gas consisting of carbon monoxide, carbon dioxide, hydrogen, methane, water, nitrogen, along with contaminants like small char particles, ash and tars. The gas is cleaned to make it suitable for use in boilers, engines and turbines to produce heat and power (CHP).
Biomass gasification provides a means of deriving more diverse forms of energy from the thermochemical conversion of biomass than conventional combustion. The basic gasification process involves devolatization, combustion and reduction.
During devolatization, methane and other hydrocarbons are produced from the biomass by the action of heat which leaves a reactive char.
During combustion, the volatiles and char are partially burned in air or oxygen to generate heat and carbon dioxide. In the reduction phase, carbon dioxide absorbs heat and reacts with the remaining char to produce carbon monoxide (producer gas). The presence of water vapour in a gasifier results in the production of hydrogen as a secondary fuel component.
There are two main types of gasifier that can be used to carry out this conversion, fixed bed gasifiers and fluidized bed gasifiers. The conversion of biomass into a combustible gas involves a two-stage process. The first, which is called pyrolysis, takes place below 600°C, when volatile components contained within the biomass are released. These may include organic compounds, hydrogen, carbon monoxide, tars and water vapour.
Pyrolysis leaves a solid residue called char. In the second stage of the gasification process, this char is reacted with steam or burnt in a restricted quantity of air or oxygen to produce further combustible gas. Depending on the precise design of gasifier chosen, the product gas may have a heating value of 6 – 19 MJ/Nm3.
Layout of a Typical Biomass Gasification Plant
The products of gasification are a mixture of carbon monoxide, carbon dioxide, methane, hydrogen and various hydrocarbons, which can then be used directly in gas turbines, and boilers, or used as precursors for synthesising a wide range of other chemicals.
In addition there are a number of methods that can be used to produce higher quality product gases, including indirect heating, oxygen blowing, and pressurisation. After appropriate treatment, the resulting gases can be burned directly for cooking or heat supply, or used in secondary conversion devices, such as internal combustion engines or gas turbines, for producing electricity or shaft power (where it also has the potential for CHP applications).
You know the saying: One person’s trash is another’s treasure. When it comes to recovering energy from municipal solid waste — commonly called garbage or trash— that treasure can be especially useful. Instead of taking up space in a landfill, we can process our trash to produce energy to power our homes, businesses and public buildings.
In 2015, the United States got about 14 billion kilowatt-hours of electricity from burning municipal solid waste, or MSW. Seventy-one waste-to-energy plants and four additional power plants burned around 29 million tons of MSW in the U.S. that year. However, just 13 percent of the country’s waste becomes energy. Around 35 percent is recycled or composted, and the rest ends up in landfills.
Recovering Energy Through Incineration
The predominant technology for MSW-to-energy plants is incineration, which involves burning the trash at high temperatures. Similarly to how some facilities use coal or natural gas as fuel sources, power plants can also burn MSW as fuel to heat water, which creates steam, turns a turbine and produces electricity.
Several methods and technologies can play a role in burning trash to create electricity. The most common type of incineration plant is what’s called a mass-burn facility. These units burn the trash in one large chamber. The facility might sort the MSW before sending it to the combustion chamber to remove non-combustible materials and recyclables.
These mass-burn systems use excess air to facilitate mixing, and ensure air gets to all the waste. Many of these units also burn the fuel on a sloped, moving grate to mix the waste even further. These steps are vital because solid waste is inconsistent, and its content varies. Some facilities also shred the MSW before moving it to the combustion chamber.
Another method for converting trash into electricity is gasification. This type of waste-to-energy plant doesn’t burn MSW directly, but instead uses it as feedstock for reactions that produce a fuel gas known as synthesis gas, or syngas. This gas typically contains carbon monoxide, carbon dioxide, methane, hydrogen and water vapor.
Approaches to gasification vary, but typically include high temperatures, high-pressure environments, very little oxygen and shredding MSW before the process begins. Common gasification methods include:
Air-fed systems, which use air instead of pure oxygen and temperatures between 800 and 1,800 degrees Celsius.
Plasma or plasma arc gasification, which uses plasma torches to increase temperatures to 2,000 to 2,800 degrees Celsius.
Syngas can be burned to create electricity, but it can also be a component in the production of transportation fuels, fertilizers and chemicals. Proponents of gasification report that it is a more efficient waste-to-energy method than incineration, and can produce around 1,000 kilowatt-hours of electricity from one ton of MSW. Incineration, on average, produces 550 kilowatt-hours.
Challenges of MSW-to-Energy
Turning trash into energy seems like an ideal solution. We have a lot of trash to deal with, and we need to produce energy. MSW-to-energy plants solve both of those problems. However, a relatively small amount of waste becomes energy, especially in the U.S.
Typical layout of MSW-to-Energy Plant
This lack may be due largely to the upfront costs of building a waste-to-energy plant. It is much cheaper in the short term to send trash straight to a landfill. Some people believe these energy production processes are just too complicated and expensive. Gasification, especially, has a reputation for being too complex.
Environmental concerns also play a role, since burning waste can release greenhouse gases. Although modern technologies can make burning waste a cleaner process, its proponents still complain it is too dirty.
Despite these challenges, as trash piles up and we continue to look for new sources of energy, waste-to-energy plants may begin to play a more integral role in our energy production and waste management processes. If we handle it responsibly and efficiently, it could become a very viable solution to several of the issues our society faces.
Are you the owner of an RV, SUV, car, boat or other vehicle, and want to be able to watch TV, cook, or power a laptop onboard? If yes, you’ll be needing a power inverter. But what are they, and what do they do? Read on to find out why you’ll need one to power your gadgets on the road…
What is a Power Inverter?
Basically, they are devices that turn your vehicle battery’s direct current (DC) into alternating current (AC) – the kind of electricity you have in outlets in your house, that are connected to the energy grid.
Having a power converter means you can plug in your appliances and devices, and power them like you would through an electricity outlet in a house.
In your car, you can get USB adaptors for your cigarette lighter so that you can charge your phone or plug in your satnav. But for larger gadgets and electronics with proper plugs, you’ll need an inverter.
Working of a Power Inverter
Like we said, they convert currents to a type safe for use in vehicles. Your vehicle’s battery voltage provides a current that powers its internal workings – you’ll need to know which voltage your vehicle’s battery uses to choose the correct inverter.
The current supplied by a battery sticks on one circuit, in one direction – where the name ‘direct current’ comes from.
However, to power your gadgets, you’ll need alternating current, as those electronics need more power to function than the DC can provide. They’re made to function with the high-voltage AC current supplied in homes.
Power inverters increase the DC voltage, change it to AC, then use it to power your devices. They amp up your battery’s voltage so you can play video games and use a kettle in your RV. Cool, huh?
These babies come in a variety of sizes – most commonly 1000, 3000 or 5000 watts.
It’s recommended that a 3000 watt inverter is the happy medium between inverter sizes and best choice to get. They’re not too small like the 1000, or too powerful and overcharged like the 5000. If you need a little extra boost, there are 3500 watt capacities available.
Find the best 3000 watt inverter for your vehicle by checking out the useful comparison guide by Solar Know How.
Modified or Pure Sine Wave Inverter?
Besides the sizing, there are two main types of inverter – the modified sine wave, and the pure sine wave.
So, what’s the difference, and which one will you need?
Modified Sine Wave: These tend to be cheaper, and less powerful. However, they’re good for most everyday electronics you will want to use, just not very large ones.
Pure Sine Wave: These are compatible with pretty much all electronics, gadgets, and appliances, and produce a powerful current most like the one supplied by the electric grid. These are the most common choice, because they’re more likely to be compatible with anything you need to plug in.
Power inverters are useful for charging on the road without having to cart around adaptors and large plugs
Other Features and Tips
Power inverters are especially useful if you are setting up a solar power system – they convert energy from the sun into electricity you can use to power your gadgets within your vehicle. This is renewable energy that isn’t a drain on your vehicle’s battery.
Power inverters aren’t just for vehicles – if you have a small cottage or outhouse, they’re very useful for setting up a small power source there.
Many (but not all) power inverters come with USB outlets, useful for charging on the road without having to cart around adaptors and large plugs. For ease of use, get one compatible with USB.
The best inverters have digital screens which show you how much energy has been consumed and information about battery voltage. It’s useful to know these things at a glance, so consider getting one that has a screen.
Modern inverters have been made to be extra-quiet, so you won’t be woken up by a noisy machine while trying to simultaneously get some sleep and charge your phone in your RV.
Considering the fact that Pakistan is among the world’s top-10 sugarcane producers, the potential of generating electricity from bagasse is huge. Almost all the sugar mills in Pakistan have in-house plants for cogeneration but they are inefficient in the consumption of bagasse. If instead, high pressure boilers are installed then the production capacity can be significantly improved with more efficient utilization of bagasse.
However, due to several reasons; mostly due to financing issues, the sugar mill owners were not able to set up these plants. Only recently, after financial incentives have been offered and a tariff rate agreed upon between the government and mill owners, are these projects moving ahead.
The sugar mill owners are more than willing to supply excess electricity generated form the in-house power plants to the national grid but were not able to before, because they couldn’t reach an agreement with the government over tariff. The demand for higher tariff was justified because of large investments in setting up new boilers. It would also have saved precious foreign exchange which is spent on imported oil.
By estimating the CDM potential of cogeneration (or CHP) projects based on biofuels, getting financing for these projects would be easier. Renewable energy projects can be developed through Carbon Development Mechanism or any other carbon credit scheme for additional revenue.
Since bagasse is a clean fuel which emits very little carbon emissions it can be financed through Carbon Development Mechanism. One of the reasons high cogeneration power plants are difficult to implement is because of the high amount of costs associated. The payback period for the power plants is unknown which makes the investors reluctant to invest in the high cogeneration project. CDM financing can help improve the rate of return of the project.
Bagasse power plants generate Carbon Emission Reductions in 2 ways; one by replacing electricity produced from fossil fuels. Secondly if not used as a fuel, it would be otherwise disposed off in an unsafe manner and the methane emissions present in biomass would pollute the environment far more than CO2 does.
Currently there are around 83 sugar mills in Pakistan producing about 3.5 million metric tons of sugar per annum with total crushing capacity 597900 TCD, which can produce approximately 3000 MW during crop season Although it may seem far-fetched at the moment, if the government starts to give more attention to sugar industry biomass rather than coal, Pakistan can fulfill its energy needs without negative repercussions or damage to the environment.
However some sugar mills are opting to use coal as a secondary fuel since the crushing period of sugarcane lasts only 4 months in Pakistan. The plants would be using coal as the main fuel during the non-crushing season. The CDM effect is reduced with the use of coal. If a high cogeneration plant is using even 80% bagasse and 20% of coal then the CERs are almost nullified. If more than 20% coal is used then the CDM potential is completely lost because the emissions are increased. However some sugar mills are not moving ahead with coal as a secondary fuel because separate tariff rates have to be obtained for electricity generation if coal is being used in the mix which is not easily obtained.
Pakistan has huge untapped potential for bagasse-based power generation
One of the incentives being offered by the State Bank of Pakistan is thatif a project qualifies as a renewable project it is eligible to get loan at 6% instead of 12%. However ones drawback is that, in order to qualify as a renewable project, CDM registration of a project is not taken into account.
Although Pakistan is on the right track by setting up high cogeneration power plants, the use of coal as a secondary fuel remains debatable. The issue that remains to be addressed is that with such huge amounts of investment on these plants, how to use these plants efficiently during non-crushing period when bagasse is not available. It seems almost counter-productive to use coal on plants which are supposed to be based on biofuels.
With the demand for energy in Pakistan growing, the country is finally exploring alternatives to expand its power production. Pakistan has to rely largely on fossils for their energy needs since electricity generation from biomass energy sources is considered to be an expensive option despite abundance of natural resources. However by focusing on growing its alternate energy options such as bagasse-based cogeneration, the country will not only mitigate climate change but also tap the unharnessed energy potential of sugar industry biomass.
During the first quarter of 2017, workers installed a wind turbine somewhere in the US every 2.4 hours. Wind provided 5.6% of all the electricity produced in the US in 2016. That’s more than double the amount of wind power in 2010. The whole world is seeing similar growth. The wind industry isn’t without controversy. Critics blame it for the scope of a blackout in Australia. On the other hand, international oil companies have begun to build off-shore wind farms.
Critics’ case against wind energy
According to its critics, wind power is unreliable. The wind doesn’t blow all the time. It doesn’t blow on any predictable pattern. Wind turbines require some minimum wind speed for them to work at all. And if the wind is too strong, they can’t operate safely and must shut down.
Wind can cross one or the other of these thresholds multiple times a day. They operate at full capacity for only a few hours a year. So the theoretical capacity of a wind farm greatly exceeds its actual output.
The times turbines can generate electricity do not coincide with rising and falling demand for electricity. This variability creates problems for stabilizing the grid. Critics further claim that the wind industry can’t operate without massive government subsidies.
Wind power and South Australia blackout of 2016?
South Australia depends on wind energy for about 40% of its electricity. It suffered seven tornadoes on September 28, 2016. Two of them, with winds almost as fast as Hurricane Katrina, destroyed twenty towers that held three different transmission lines. Nine wind farms shut down. Within minutes, the entire state suffered a massive blackout.
What contributed the most to the blackout? South Australia’s high dependence on wind power? The weather? Or something else?
Renewable energy skeptics quickly claimed the blackout justified their position. The wind farms simply failed to provide enough electricity in the emergency. Wind and solar energy, they say, are inherently unreliable. South Australia’s heavy reliance demonstrates an irresponsible policy based on ideology more than technological reality.
Certainly, the weather would have caused a disturbance in electrical service no matter what source of electricity. People near the downed transmission lines could not have avoided loss of power. But prompt action by grid operators makes it possible to bypass problem areas and limit the extent of the outage.
On closer examination, however, the correct answer to the multiple-choice question above is C: something else.
Wind turbines have “low voltage ride through” settings to keep operating for brief periods when voltage dips below the threshold at which they can operate correctly. If low-voltage conditions occur too frequently, the turbines have a protection mechanism that turns them off.
Ten wind farms experienced between three and six low-voltage events within two minutes. But the turbines were operating on factory settings. No one performed any testing to determine good settings under local conditions.
The agency that regulates the Australian electricity market knew nothing about the protection feature. It blamed the wind farms, but surely someone on staff should have been familiar with the default operation of the turbines. After all, the agency approved purchase and installation of the turbines. It had all the documentation.
Two gas generating plants that should have supplied backup power failed to come online.
The weather caused a problem that became a crisis not because of technical limitations of renewable energy, but because of too many different organizations’ incompetence.
If the wind is too strong, wind turbines can’t operate safely and must shut down.
One homeowner in South Australia didn’t suffer from the outage. He didn’t even know about the blackout till he saw it on the news. He had to test the accuracy of the news reports by opening his oven and noting that the light didn’t come on.
It turns out he had installed solar panels just a few weeks earlier. And since power outages in his part of South Australia occur almost every month, he decided to install a Tesla Powerwall as well.
He can’t use it to power his entire house, but it takes care of the lights and the television. It stores enough electricity for 10 hours of off-grid power.
Big oil and wind power
International oil companies have not joined the chorus of wind-industry skeptics. Several of them, including Royal Dutch Shell, have begun to invest heavily in off-shore wind farms. Especially in the North Sea. Oil production there has steadily declined for about 15 years.
Exploring for new oil fields has become too risky and expensive. These oil companies have decided that investing in wind energy helps their cash flow and makes it more predictable.
Oil companies have more expertise in working on offshore platforms than do companies that specialize in wind energy. Instead of building a foundation for turbines on the ocean floor, at least one oil company has begun to explore how to mount them on floating platforms.
Traditional wind energy firms have been operating turbines in the North Sea for years, but the oil companies have begun to outbid them. Their off-shore expertise has helped them drive down their costs.
So far, American oil companies have shown less interest in wind farms. If they decide they’re in the oil business, they will eventually lose market share to renewable energy companies. If they decide they’re in the energy business, they’ll have to start investing in renewable energy. And if any decide to invest heavily in solar power besides or instead of wind, they will still be following the lead of Total, a French oil company.
For that matter, the coal business is dying. Perhaps some of them will have enough sense to invest in renewables to improve their cash flow.
While fuel and electricity costs rise, many households are moving to solar power systems. The easiest solution that one can find is to opt for solar panel systems.
Curious about what solar panel systems are?
Sunshine is available to using abundance, and solar systems use efficient technology to harvest and turn this energy into electricity with pre-defined methods. Solar power panels serve the purpose of collecting solar energy and converting it through the photovoltaic (PV) effect into electric power. Many homes have a roof or backyard, which can be used for installing solar systems to generate electricity.
A home solar system must provide ample electrical energy to meet all home power needs. It provides AC power, as typically all households use AC power to operate lighting systems, electronics, appliances and machinery such as machines, refrigerators, mixers, fans, air conditioners, TVs and music systems.The price of the home solar power plant varies on its size and type.
On-grid and off-grid solar systems come in two types of solar power plants. Let’s look at the difference between the two:
1. Off-Grid Solar System
An off-grid solar system is well designed to generate enough power throughout the year to meet the needs of a household, even in the depths of winter, when there is less sunshine. However, since there is no electricity grid connection to an off-grid solar system, battery storage is necessary.
The high cost of batteries and inverters implies that the off-grid solar system is costly than the alternatives, so they are usually needed only in more remote areas far from the grid. Nevertheless, battery costs are reducing at a high rate, so the demand for an off-grid solar system is now increasing, even in cities and towns.
Advantages of An Off-Grid Solar System
Such an off-grid solar system can function independently and not rely on the grid.
They generate enough electricity that can be collected and used at night.
These are suitable for remote areas that do not have grid power access.
Shutdowns and infrastructure faults won’t affect the power supply.
2. On-Grid Solar System
On-grid solar systems are the most widely solar product used by homeowners. Such systems do not need batteries and are connected to the public electricity grid and use solar inverters. Any surplus solar power you produce is sold to the electricity grid, and the energy you sell is usually paid a feed-in tariff (FiT) or credits.
Unlike an off-grid solar system, because of safety reasons, these are unable to work or generate electricity during a blackout. Because blackouts usually occur when the electricity grid is disabled, if the solar inverter had fed energy into a broken grid, it would endanger the safety of the people fixing the network’s faults. Most on-grid solar systems with battery storage can separate itself from the grid (known as islanding) and continue to supply some power during a blackout.
Advantages of An On-Grid Solar System
On-grid solar systems are incredibly cost-effective and easy to install.
Residential users can earn a passive income for the surplus energy generated by the system.
Choose Between On-Grid & Off-Grid Solar Systems to Fit Your Needs
Solar power systems are a form of clean, renewable energy, and they have many benefits depending on the type of system you chose. Knowing the advantages of both an on-grid and off-grid solar system, you can select the one according to your needs. With the right solar system and proper installation, you can have clean and cost-effective energy, without being worried about maintenance problems.
