Wind turbines, like many other human activities and buildings, also increase the death rate of avian creatures such as birds and bats. A summary of the existing field studies compiled in 2010 from the National Wind Coordinating Collaborative identified fewer than 14 and typically less than four bird deaths per installed megawatt per year, but a ...
The factors that determine tropical cyclone activity are relatively well understood: warmer sea levels are favourable to tropical cyclones, as well as an unstable and moist mid-troposphere, while vertical wind shear suppresses them. All of these factors will change under climate change, but is not always clear which factor dominates.
Human activities have substantial impact on coral reefs, contributing to their worldwide decline. [148] Damaging activities encompass coral mining, pollution (both organic and non-organic), overfishing, blast fishing, as well as the excavation of canals and access points to islands and bays.
Among all human activities, fossil fuel combustion is the largest contributor to the ongoing buildup of carbon in the Earth's biosphere. [37] The International Energy Agency and others report that oil & gas use comprises over 55% (18 billion tons) of the recorded 32.8 billion tons (BT) of CO 2 released into the atmosphere from all energy ...
Environmental issues are harmful aspects of human activity on the biophysical environment. This alphabetical list is loosely divided into causes, effects and mitigation, noting that effects are interconnected and can cause new effects.
The federal government has ordered an offshore wind developer off Nantucket Island, a popular summer tourist destination in Massachusetts, to suspend operations after parts of a damaged turbine ...
Wind turbines have some of the lowest global warming potential per unit of electricity generated: far less greenhouse gas is emitted than for the average unit of electricity, so wind power helps limit climate change. [59] Wind power consumes no fuel, and emits no air pollution, unlike fossil fuel power sources. The energy consumed to ...
The 5 GW Rampart Dam was terminated as a result of concerns about indigenous people and ecological conservation issues. Policy makers often debate the constraints and opportunities of renewable energy. Renewable electricity production, from sources such as wind power and solar power, is sometimes criticized for being variable or intermittent.
