It is remarkable how resistant humankind has become to working with nature, all too often preferring to dominate and exploit the world around us – a trait which is detrimental to human and non-human life in the long run. Thankfully, more and more people are waking up to the idea that it is the processes and lessons of the natural world, rather than its exploitable properties, which are our most valuable assets.
As the renewable energy movement becomes truly mainstream, everyday people are beginning to turn their backs on the excesses of 19th and 20th century consumption and to instead look forwards and embrace an ecosystem of which we are not the master – but rather just another essential component.
One in way in which you can do so is to take a stand against the decimation of bee populations in a constructive manner – by making your garden a bee-friendly place. Patterns and techniques of crop farming have left the insects in increasingly hostile territory, with bee numbers falling dramatically enough to hit the headlines. But it’s possible even for individuals to make a difference just by the flowers and plants they choose to put in their garden.
Bees are crazy for the kinds of wildflowers that have been torn up by industrial-level farming, and a good variety of local, colorful blooms can brighten your days while providing a delicious stopping point for the stripy critters. Even just allowing your garden to grow naturally – without clamping down on weeds and dandelions – can make it a more inviting environment for the right kinds of insects.
Bees are crazy for wildflowers
While it’s okay to use a smattering of non-native plants in your garden, this should always be done in sensitivity to the surrounding area, as unwelcome plant-life can create environmental imbalances. If in doubt, stay local – and consult this new chart from Budget Direct, which lists some of the best choices you can make for the bees in your garden, wherever you are in the world.
Wind power is the second most widely used renewable energy source in the U.S., just behind hydropower. Unlike solar, wind power creates little to no pollution and requires very little maintenance. However, it has one significant problem — a detrimental effect on wildlife and the local ecosystem.
Industrial wind farms wreak havoc on bird and bat populations, plus they pose an ecological disturbance to the land. While the energy generation is incredibly sustainable, the influence turbines have on local wildlife populations adds controversy to the success of this energy source.
The future implementation of wind as a leading source of energy will depend on our ability to reduce its ecological footprint. Employing best practices that work to minimize adverse effects on local habitats will play an integral role in the construction of new farms.
Determining the exact impact of wind turbines on wildlife is hard to discern. The number of birds and bats killed from direct contact is only one variable. The long-term effects on food chain supplies, population and habitats are hard to quantify. The first step in reducing the environmental impact is determining where the influence is greatest.
Research estimates that in North America alone, wind turbines kill an estimated 140,000 to 328,000 birds each year. This statistic does include other flying creatures, like bats, whose populations have been significantly affected by wind farms.
Bats are essential to the function of our ecosystem and food system. In 2015, the American Wind Energy Association (AWEA) added guidelines about the voluntary process of halting turbines at lower speeds during periods of the night when these animals are most active. These efforts may reduce deaths by up to 30%, though research demonstrates an extra delay could potentially increase that number to 90%.
Land Use Planning
Close attention to site selection and preparation may curtail the consequences of wind farms on the surrounding environment. Construction is a major ecosystem disruptor, as installing transmission lines and removing soil can hurt plants and animals in the vicinity. Experts encourage many wind companies to engage in erosion control practices, which includes re-establishing native vegetation and other restoration techniques.
Wind farms are generally criticized by their inflexibility when it comes to site location. Compared to solar panels, which can be installed on buildings and utilized across a diverse array of environments, wind farms are more limited. One benefit, however, is that people can establish these turbines on abandoned industrial land. The ability to re-purpose previously degraded land with a renewable energy source is a victory for wildlife and humans alike.
If the wind is too strong, wind turbines can’t operate safely and must shut down.
A final consideration when it comes to reducing ecological impact includes preventative measures, such as monitoring a habitat before construction. By tracking the environment before breaking ground, builders can better determine the best location for the farm.
As wind power becomes a cost-effective and energy-efficient option, advanced technology will lessen the impact of turbines on wildlife. According to U.S Energy Information Administration, the wind industry is collaborating with the U.S government to find optimization solutions.
Several ways exist in which wind farms can reduce their impact on local habitats and take preventative steps affecting animal and bird populations. One example includes Ultrasonic Acoustic Deterrents (UADs), which emit a loud noise that deters bats but is incomprehensible to the human ear.
Other solutions include painting wind turbines purple or shining ultraviolet lights on the structures to alert migratory species. Some manufacturing companies plan to make innovations in how to construct these structures. Changes include alterations to the blade surfaces and more sound-absorbent materials.
A Comprehensive Approach
The cost of wind power has dropped almost 50% in the last four years. With an increased incentive to invest in renewables, experts predict the number of wind farms around the world to grow rapidly in the next decade.
Wind power has many benefits, one of which being that, unlike solar, return on investment for the production and installation of turbines is five to eight months, with each structure designed to produce for at least twenty years. With an increase in implementation, the ecological impact is unavoidable. As a result, the focus will be on reducing the footprint of wind turbines, rather than decreasing their utilization as an energy source.
