Reducing Ecological Impact of Wind Turbines
Introduction
As we search for alternatives to the fossil fuels currently driving mass extinction and historic temperature swings on our planet, it is vital to make sure we don't switch from one poor choice to another. Wind turbines are highly efficient and minimizes a lot of ecological damage currently caused by humanity's hunger for energy, however there are several negative effects that this power source has on the environment. This page is intended to discuss scientifically supported methods for reducing the impact of wind turbines, including the installation process and waste cycle.
Reducing Impact by Topic
Bats
Resources
The following are listed in the chronological order order in which you would want/need to implement them.
Pre-Construction Acoustic Surveys "Acoustic monitoring allows researchers to detect and record calls of echolocating bats, which can be used to assess relative activity and identify species or groups of species. Understanding bat activity levels prior to construction of wind energy facilities may assist in identifying habitats and features that pose a high risk of fatality and aid with decision-making, including specific placement of turbines.
Pre-construction surveys at wind energy facilities commonly deploy acoustic detectors to assess local bat species and activity. However, using this information to predict bat fatality and, thus, risk at a site has proved to be challenging.
BWEC researchers have conducted several studies to assess whether pre-construction monitoring for bat presence and activity can predict post-construction fatality."
Ocean Installment
Marine Spatial Planning
This can be an important strategic step for preventing interference with wildlife before construction even begins. Working with local communities, government agencies, conservation groups and scientists is critical for creating successful and effective marine spatial plans.
Marine Noise Pollution
This type of noise pollution can harm organisms from the algae on which the food web relies, to the coral that clean our oceans, all the way up to large marine mammals. This harm can range from smaller issues like challenges with finding food or communicating with other creatures, to painful deaths caused by sonic surveys (for the fossil fuel industries).
One surprisingly cheap yet effective tool against this issue is the use of bubble curtains, which is already a legal requirement for wind turbine installments in certain countries.
Bubble Curtains
The consist of hoses that are laid across the bottom of the ocean, allowing bubbles to spill upward, creating a "bubble curtain" that helps muffle noise pollution, without any risk of entanglement to endangered species such as whales or dolphins.
Organizations
North America
USA
The Bats and Wind Energy Cooperative (BWEC) "is an alliance of experts from government agencies, private industry academia, and non-governmental organizations that cooperate to advance and disseminate science-based solutions to cost effectively quantify and mitigate the impact of wind turbines on bats."
