How to Make the Pharmaceutical Industry More Sustainable

The pharmaceutical industry has a substantial impact on the environment, especially when the materials used to make them and the chemicals that comprise make their way directly into the environment. The pharmaceutical industry at large as well as average consumer can take steps to make of use of medicine more sustainable through both significant and relatively minor changes.

Medicines and the Environment

The drugs that we consume naturally enter our environment as our body turns them to waste. This issue becomes exacerbated when people intentionally dispose of unused medicine by flushing it down the drain.

Although our water treatment systems are designed to take contaminants out of our wastewater before we re-introduce to the natural environment, some still get through. These contaminants, which include those in medications, can damage the ecosystems they end up in.

High levels of estrogen in waters due to birth control, for example, can hamper the ability of fish to reproduce, reducing their population size. Once those chemicals find their way into the water, they enter the food chain and eventually impact animals that live on land too, including humans.

Plants will absorb the chemicals from medications. Animals then eat these plants or drink the water and ingest the contaminants. Humans might drink the water or eat the plants or animals, making pollution from pharmaceuticals a human health hazard as well. This problem becomes worse in the summer when livestock such as cattle require two to three times as much water as they do during other times of the year.

Proper Disposal of Medicines

If you have unused medications that you need to get rid of, don’t flush them down the drain or throw them straight into the trash. The U.S. Food and Drug Administration (FDA) recommends one of several other options for the safe and sustainable disposal of medicines.

Some communities have drug take-back programs that the Drug Enforcement Administration (DEA) approves. Some pharmacies also allow you to mail in or dispose of unused medications at kiosks. The DEA also organizes a national drug take-back day.

Although certain medications have recommendations on the label to flush them, you can dispose of the majority of them in your regular trash at home. The FDA recommends mixing them with something unpalatable such as dirt, kitty litter or coffee grounds in a plastic bag that you can seal. This disguises the drugs and prevents pets from getting into them. You can then throw the bag away.

If you are a throwing away a prescription medication container, be sure to scratch out all potentially identifying information to protect your privacy and identity.

Using Medicines More Sustainably

Another option for reducing the impact your use of medicine has on the environment is to use less of it or use more environmentally friendly medications.

To use less medicine, only use it when you truly need it and try substituting natural remedies for pharmaceuticals. Reach for naturally derived treatments such as essential oils, vitamins, herbs or a cup of hot tea. Always consult with your doctor before changing your medication regimen.

As a long-term strategy, regular exercise and a healthy diet can do wonders in improving your overall health and decreasing your need to take medicines.

Sustainability from the Industry’s Perspective

Of course, making the pharmaceutical industry more sustainable isn’t the sole responsibility of the consumer. The industry can also change its practices to manage pharmaceuticals in a more eco-friendly fashion.

One aspect of this involves energy use. The manufacturing and transportation of medications can be extremely energy-intensive. By using energy more efficiently and using cleaner energy, drug companies can reduce their environmental impact.

Pharmaceutical industry can change its practices to manage pharmaceuticals in a more ecofriendly manner.

These corporations can also make an effort to include more eco-friendly substances in their medications. While they may not be able to remove every non-natural chemical from their products, they can offer greener alternatives to consume and look into reducing the presence of damaging substances as much as possible.

This applies not only to the organizations closest to the consumers but to the entire supply chain.

Medications are often vital to our health, but it can also have a negative impact on the health of our environment. Taking steps to manage pharmaceuticals more sustainably can enable us to protect our own well-being as well as that of our environment.

Waste Management in Sweden: Perspectives

Sweden is considered as a global leader in sustainable waste management and in the reduction of per capita carbon footprint. The country consistently works to lower its greenhouse gas emissions, improve energy efficiency and increase public awareness. Over the past 10 years, Sweden developed methods of repurposing waste, so less than one percent of the total waste generated in the country makes it to landfills. To accomplish this, the country changed their perspective of garbage.

Increase Recycling

Recycling is a part of Swedish culture. Residents regularly sort recyclable materials and food scraps from other waste in their homes before disposal. This streamlines the recycling process and reduces the effort required to sort large volumes of waste at larger recycling centers. As another way to promote recycling, the Swedish government created legislation stating recycling centers must be within 1,000 feet of residential areas. Conveniently located facilities encourage citizens to properly dispose of their waste.

Repurpose Materials

Citizens are also encouraged to reuse or repurpose materials before recycling or disposing of them. Repurposing and reusing products requires less energy when compared to the recycling or waste disposal process. As Swedes use more repurposed products, they reduce the volume of new products they consume which are created from fresh materials. In turn, the country preserves more of its resources.

Invest in Waste to Energy

Over 50 percent of the waste generated in Sweden is burned in waste-to-energy facilities. The energy produced by these facilities heats homes across the country during the long winter months. Localized heating — known as district heating — has improved air quality throughout the nation. It’s easier and more economical to control the emissions from several locations as opposed to multiple, smaller non-point sources.

Another benefit of waste-to-energy facilities is that ash and other byproducts of the burning process can be used for road construction materials. As a whole, Sweden doesn’t create enough waste to fuel its waste to energy plants — the country imports waste from its neighbors to keep its facilities going.

In the early 1990’s, the Swedish government shifted the responsibility for waste management from cities to the industries producing materials which would eventually turn to waste. To promote burning waste for energy, the government provides tax incentives to companies which make more economically attractive.

Impact of Waste-to-Energy

Although Sweden has eliminated the volume of trash entering landfills, they have increased their environmental impacts in other ways. Waste-to-energy facilities are relatively clean in that most harmful byproducts are filtered out before entering the environment, though they still release carbon-dioxide and water as their primary outputs. On average, waste-to-energy plants generate nearly 20 percent more carbon-dioxide when compared to coal plants.

 

waste-management-sweden

Coal plants burn and release carbon which is otherwise sequestered in the ground and unable to react with the earth’s atmosphere. Waste-to-energy facilities consume and release carbon from products made of organic materials, which naturally release their carbon over time. The downside to this process is that it frees the carbon from these materials at a much faster rate than it would be naturally.

The reliance on the waste-to-energy process to generate heat and the tax incentives may lower Swedish motivation to recycle and reuse materials. The country already needs to import trash to keep their waste-to-energy plants running regularly. Another disadvantage of this process is the removal and destruction of finite materials from the environment.

Even though Sweden continues to make strides in lowering their environmental impact as a whole, they should reevaluate their reliance on waste to energy facilities.

Recycling of Lead-Acid Batteries in Developing Countries

Lead-acid batteries (also known as LABs) are a common item in our daily lives. Once the lead of the battery is timed out, we have no option but to dump it because it has no use for us anymore, but the copper plates in the battery remain reusable which can be used for recycling. There are some disagreements about the benefits of recycling battery, say alkaline battery, over simple disposal because the mercury in the battery no longer exists and the disposal material is abundant and non-toxic. But for automotive batteries the scenario is different in terms of benefits. The recycling of this type of battery holds both economic and environmental benefits.

lead-acid-battery-recycling

The reusable material from the used battery is removed and recycled which reduces the needs for raw materials which is originally imported from abroad. It creates a balance payment and cost. In addition to this there can be considerable environmental impact during mining processes such as emission from smelting of sulfide ore, copper, nickel, and cobalt and this can be eliminated if recycling can be introduced.

Dangers of Lead-Acid Batteries

LABs generally consist of both sulphuric acid and large amount of lead which is not only corrosive but also a good carrier for soluble lead and lead particles. Lead is highly toxic metal which causes a wide range of adverse health effect especially on young children. If one gets expose excessively to lead it can cause damage to brain and kidney, impair hearing, and can led to various other associated problems. On an average an automobile manufactured contain about 12kg of lead, in which about 96% of lead is used in lead acid battery and remaining 4% is used in other applications like wheel balance weight, protective coating and variation dampers.

Both lead and cadmium are harmful for human health and environment. This toxic substances seeps into the soil, groundwater and surface water through landfill and also releases toxins into the air when they are burnt in municipal waste incinerators. Moreover cadmium can be easily absorbed by the pant root and get into the fruits, vegetables, and waters are consumed by animals and human beings, they can fall to prey to a host of ill effects.

Studies have shown that nausea, excessive salivation, abdominal pain, liver and kidney damage, skin irritation, headaches, asthma, nervousness, decreased IQ in children, and sometimes even cancer can result from exposure to such metals for a sufficient period of time.

Need for Effective Control Measures

In a battery recycling plant, effective control measures need to be implemented, both to protect the health of workers and to prevent pollution of the environment. Good plant design, with reduction of the potential for the emission of contaminating substances is of utmost importance and the newer smelting processes are inherently much cleaner than traditional blast furnaces.

Pollution abatement technologies, including the treatment of exhaust gases and liquid effluents, need to be installed. Those mostly exposed to releases within the plants are the workforce. Control measures such as maintaining minimum standards of air quality within the works, medical surveillance of employees, use of protective equipment, and provision of conditions of good hygiene in general, is necessary to avoid occupational lead exposure. However, few government/non-governmental steps have been taken yet; rather this practice is a traditional trading system as prevail in the society.

Positive and Negative Impacts

In developing countries such as Bangladesh, recycling or reusing of used lead-acid batteries has both positive and negative impact on environment. Positive impact is that, if battery is recycled in proper and in sustainable manner it saves environment from toxic material of battery, otherwise battery waste is dumped into the landfills. Negative impact is that if recycling is not done in sustainable manner emits gases produced from battery recycling has adverse impacts on environment and human being.

In a battery recycling plant, effective control measures are required to safeguard public health and environment.

Direct recycling process should be banned as it has adverse impact on environment. As it is an illegal process, shopkeepers perform this process in hidden way. Government should impose the law and regulation strictly in this occurrence. This information can be used for advertising material highlighting the environmental benefits of recycling or reusing encourages the purchasing of old lead acid battery. It will accelerate the selling rate of old battery.

Importance of Awareness

Necessary steps should be taken to increase awareness about environmental impacts of used lead acid batteries. Proper instruction should be provided among the general mass. It will also increase reusing of old battery. Battery regeneration is a unique process specially designed to revive the lost capacity of batteries and give priority to choose secondary battery. Battery Reuse Centre can be developed for effective reuse and recycle.

The aim to divert reusable battery, donated by the public, which often could have been destined for landfill and instead provides a much needed source of low-cost battery to those in need. The battery reuse service encourages volunteer involvement and trainee placements in all aspects of its operation. Awareness program (posters, pamphlets, TV & radio commercials, road-shows, website, exhibitions, talks), infrastructure, information center, tax rebates for manufacturers should be taken to increase recycling or reusing of old battery.

Biomethane – The Green Gas

Biomethane, also known as the green gas, is a well-known and well-proven source of clean energy, and is witnessing increasing demand worldwide, especially in European countries, as it is one of the most cost-effective and eco-friendly replacement for natural gas and diesel.

Advantages of Biomethane

The key advantage of biomethane is that it is less corrosive than biogas which makes it more flexible in its application than raw biogas. It can be injected directly into the existing natural gas grid leading to energy-efficient and cost-effective transport, besides allowing natural gas grid operators to persuade consumers to make a smooth transition to a renewable source of natural gas.

Biogas can be upgraded to biomethane and injected into the natural gas grid to substitute natural gas or can be compressed and fuelled via a pumping station at the place of production. Biomethane can be injected and distributed through the natural gas grid, after it has been compressed to the pipeline pressure.

The injected biomethane can be used at any ratio with natural gas as vehicle fuel. In many EU countries, the access to the gas grid is guaranteed for all biogas suppliers.

A major advantage of using natural gas grid for biomethane distribution is that the grid connects the production site of biomethane, which is usually in rural areas, with more densely populated areas. This enables biogas to reach new customers.

Storage of Biomethane

Biomethane can be converted either into liquefied biomethane (LBM) or compressed biomethane (CBM) in order to facilitate its long-term storage and transportation. LBM can be transported relatively easily and can be dispensed through LNG vehicles or CNG vehicles. Liquid biomethane is transported in the same manner as LNG, that is, via insulated tanker trucks designed for transportation of cryogenic liquids.

Biomethane can be stored as CBM to save space. The gas is stored in steel cylinders such as those typically used for storage of other commercial gases.

Applications of Biomethane

Biomethane can be used to generate electricity and heating from within smaller decentralized, or large centrally-located combined heat and power plants. It can be used by heating systems with a highly efficient fuel value, and employed as a regenerative power source in gas-powered vehicles.

Biomethane, as a transportation fuel, is most suitable for vehicles having engines that are based on natural gas (CNG or LNG). Once biogas is cleaned and upgraded to biomethane, it is virtually the same as natural gas.

Because biomethane has a lower energy density than NG, due to the high CO2 content, in some circumstances, changes to natural gas-based vehicle’s fuel injection system are required to use the biomethane effectively.

Bagasse-Based Cogeneration in Pakistan: Challenges and Opportunities

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.

bagasse-pakistan

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 that if 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.

Conclusion

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.

Top 4 Benefits of Biomass Energy

Biomass is material originating from plant and animal matter. Biomass energy uses biomass to create energy by burning organic materials. The heat energy released through burning these materials can heat homes or water. Heated water produces steam, which in turn can generate electricity. Using organic materials to create heat and power is an eco-friendlier alternative compared to using fossil fuels. Here’s more about the benefits of biomass energy

biomass-bales

1. Indefinitely Renewable

The majority of the world’s energy comes from burning fossil fuels. Fossil fuels are a finite resource. Once fossil fuel resources run out, new fuel sources will be needed to meet global energy demands. Biomass offers a solution to meet this need.

Organic waste material from agriculture and logging operations, animal manure, and sludge from wastewater treatment are all viable fuels for generating biomass energy. As long as the earth is inhabited, these materials will be readily available.

2. Reduce, Reuse, Recycle

Organic waste that would typically be disposed of in landfills could be redirected for biomass energy use. This reduces the amount of material in landfills and slows the rate at which landfills are filled. Some of the most common waste products used for biomass energy are wood chips and agricultural waste products. Wood materials can easily be converted from already existing wood structures that will be destroyed, such as wooden furniture and log cabins, preferably both would also come from responsible logging and practices as well.

As more organic waste is diverted from landfills, the number of new landfills needed would be reduced. Older landfills are at risk for leaking leachate. Leachate contains many environmental pollutants that can contaminate groundwater sources.

Burning fossil fuel releases carbon into the atmosphere which was previously trapped below ground. Trapped carbon isn’t at risk for contributing to global climate change since it can’t interact with air. Each time fossil fuels are burned, they allow previously trapped carbon to enter the atmosphere and contribute to global climate change. In comparison, biofuel is carbon-neutral.

The materials used to create biomass energy naturally release carbon into the environment as they decompose. Living plants and trees use carbon dioxide to grow and release oxygen into the atmosphere. Carbon dioxide released by burning organic material will be absorbed by existing plants and trees. The biomass cycle is carbon-neutral as no new carbon is introduced to the system.

3. Smaller Carbon Footprint

The amount of unused farmland is increasing as agriculture becomes more efficient. Maintaining open land is expensive. As a result, farmers are selling off their property for new developments. Unused open agricultural land could be used to grow organic material for biofuels.

Converting open tracts of land to developed areas increases the amount of storm-water runoff. Storm-water runoff from developed areas contains more pollutants than storm-water runoff from undeveloped areas. Using open areas to grow biomass sources instead of creating new developments would reduce water pollution.

Biomass-Resources

A quick glance at popular biomass resources

Forested areas also provide sources of biofuel material. Open land converted to sustainable forestry would create new animal habitats and offset carbon emissions from existing fossil fuel sources as more plants and trees would be available to absorb carbon dioxide.

4. Social Benefits of Biomass Energy

Burning fossil fuels releases sulfur dioxide, mercury and particulate matter into the atmosphere which can cause asthma, cancer and respiratory problems. Biomass energy emits less harmful byproducts compared to fossil fuels, which means cleaner air and healthier people.

Biofuel can improve rural economies by providing more people with unused land the opportunity to grown biomass material for energy use. Workers would be needed to harvest and process the materials needed to generate biofuel.

Since biomass is a renewable energy source, energy providers can receive tax credits and incentives. Countries with land resources will be less reliant on foreign fossil fuel providers and can improve their local economies.

Increasing biomass energy usage can reduce forest fires. Selectively reducing brush can still reduce the risk of wildfires spreading. Exposing underbrush and groundcover to rainfall decreases the change of it drying out and creating optimal, fire spreading conditions.

Biomass Energy in Denmark

Denmark is an example of how effective biomass energy can be in improving energy efficiency. Approximately 70 percent of renewable-energy consumption in Denmark comes from biomass.

Woody biomass creates an increasing percentage of heating from combined heat and power (CHP) plants with a goal to for 100 percent of hearing to be derived from woody biomass by 2035. Another form of biomass is agricultural biomass. This form utilizes materials such as straw and corn to create end-products like electricity, heating and biofuels.

The Danish Energy Agency has developed a plan including four scenarios that will help Denmark become fossil fuel free by 2050. The biomass scenario involves CHP for electricity and district heating, indicating that biomass energy is important in Denmark’s energy sector today and will play an increasingly important role in the future.

Biomass offers an eco-friendly and renewable method of reducing pollution and the effects of global climate change. And, like other forms of renewable energy, the products needed to develop biomass energy are readily available.

The Complete Beginner’s Guide to Furnaces

Residential heating is essential to the comfort and even health of the occupants of a house during winter. The core of any heating system is the furnace, which in most homes is located somewhere outside the main house or in the basement. This is so as to keep it out of the way but also for safety purposes. Whether you are moving into a new place and have to install a new furnace or you just wish to overhaul your current one, there are considerations to make before you go to the shop.

Types of Furnaces

Broadly speaking, there are two available types of furnaces. There is the traditional furnace and the two stage furnace. The traditional furnace, also called the single stage furnace, is either full on or completely off. This is to say that when it is on, it operates at maximum heat output and there is no way to regulate that because there is no provision for medium heat.

The two stage furnace is an improvement of this. In one setting, it can run like the traditional furnace but in the other, it allows for a reduced heat output when the temperature is not very low. If puzzling over which furnace to buy between these two, consider the following advantages and disadvantages.

Advantages and Disadvantages of Two-stage Furnace

A two stage furnace is considered quieter. This is because it runs at a functionality of 75-80 percent most of the time. Lower fan speed means less noise. It maintains a more constant temperature without dips and spikes. This kind of furnace also saves energy because it runs on the lower setting most of the time. Even with these advantages, it is said to have two key disadvantages:

  • High upfront costs – It was made to improve upon the traditional furnace. It is therefore comes as no surprise that it is more expensive than the traditional furnace.
  • It breaks down more often – Unlike a traditional furnace which goes off when the weather is moderate to warm, a two stage furnace keeps running at that low setting. Running almost constantly causes wear and tear and may lead to frequent breakdowns.

Advantages of Traditional Furnace

It may not be possible to regulate the level of heating with a traditional furnace. However, it is the go to furnace when working on a budget because it is cheaper. It also breaks down less often than the two stage furnace. Besides, modern single stage furnaces have been remodeled to make them energy efficient. This should go a long way to reduce heating costs.

Other factors to consider before purchasing a furnace are:

  • Type of fuel – If you have no gas connection or if it is interrupted often, you might want to go for an electric furnace instead of a gas furnace.
  • Prevailing weather – Consider where you live. If it is customary to have extremely cold winters, then the traditional furnace might be the best because you will have no need for the low heat setting.

The type of furnace you install should be determined by the heating needs of your household and those in it. Seek the help of a contractor so that they can advise on the appropriate type and even size of furnace.

Why You Should Be Investing in Solar Panels?

The future is green, and it’s more important to get on board with it than ever before. The past year has seen countless climate change related natural disasters, from the recent devastating mega-fires in California to frequent hurricanes sweeping the US and the Caribbean.

Solar panels are becoming much more accessible, for homeowners and for businesses. Traditional roof-rack solar panels can now be installed for as little as around $3,000, and are practically a no-brainer due to the energy savings you’ll make over time (you could even totally eliminate your electricity bill). Not to mention that you’ll be doing your part to help the environment in our planet’s time of need.

solar-energy-trends

Solar panels are becoming more accessible, for homeowners and businesses

If you’ve always found chunky solar panels ugly and off-putting, business magnate Elon Musk has a solution. His electric car and solar panel company Tesla has recently unveiled invisible solar roof tiles. The tiles look exactly like normal roof slates, but capture the sun’s energy without drawing attention. These tiles are paving the way to normalizing sustainable, beautiful eco-homes.

To further convince you about seriously considering installing solar panels for your home, check out our list of top reasons why solar panels will benefit your household or business.

Slash Your Energy Bills

After the initial investment of purchasing the panels and installation, the energy produced is all yours. Even if you consume more energy than your panels can produce, you’ll make drastic savings on what you are currently paying by purchasing all your electricity from the grid.

You’ll make even more amazing savings if you live in a sunny state or country – prices in Brisbane, Australia, are particularly low to purchase and install solar panels. And as the city enjoys on average 261 days of sun per year, panels there will produce more than enough energy to power homes all year round.

Energy costs are only set to rise and rise – meaning that by investing in solar panels now, you’ll never feel the strain of your electricity bills going up again. This is an especially smart idea for business owners with fluctuating income, as you can more easily predict your cashflow with fixed energy prices.

Increase the Value of Your Home

If you are open to the possibility of moving to a new house in the future, you will be able to sell your current property at an increased value by equipping it with solar panels. It’s an attractive prospect for buyers if a potential home comes with very small or no electricity bills, so you’ll be making a huge return on your investment in this way, too.

solar-battery

Note: Be wary of ‘renting your roof’ to solar panel companies if you can’t afford to purchase the panels outright. You may want to ‘go green’ in any way you can, but buying panels is by far the most practical way to enjoy the benefits. The lengthy leases that come with rental panel contracts (often 25 years) have been seen to put off mortgage lenders.

It’s highly recommended that if you want to benefit from free electricity and help the environment with solar, you should save up first to increase the value of your property – not render it unsellable.

Reduce Your Carbon Footprint

As we said, it’s never been so important to do your bit to save our eco-system. The polar ice caps are melting faster than has ever been recorded, and the earth is suffering terrible effects. As well as hurricanes and fires, we’ve also experienced floods, earthquakes and landslides all over the world this year.

In the large scheme of things, installing solar panels doesn’t seem like it will help much, but if everyone did their part to be more eco-conscious, we could significantly reduce the strain of destructive fossil fuels on the environment. By equipping your property with solar panels, you will save money while making steps to saving the environment – a tough offer to turn down!

Utilizing green energy within your business has even better rewards. Marketing your business as eco-conscious and sustainable is a great way to attract customers and impress existing ones. In recent years, studies into consumer activity have found that sustainability is a big shopping priority, especially among the millennial generation. Corporate solar panels will increase your revenue by expanding your customer base AND saving your business’s energy bills.

So – what are you waiting for? Contact a solar energy company today, who will be more than happy to assist you on your green energy journey.

A Blackout, Big Oil, and Wind Energy

The annual wind turbine capacity additions in the United States totaled 14.2 gigawatts, surpassing the previous record of 13.2 GW added in 2012. 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-farm-Lake-Turkana-Kenya

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 wind 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.
