How does nuclear energy affect the environment?
With 100 nuclear plants across the United States, nuclear energy produces a whopping 20% of the country’s energy, and although nuclear energy has the advantage of not producing carbon dioxide , it comes with its own very high risks. Nuclear power plants produce uranium mill tailings, reactor fuel, and other wastes that remain radioactive for centuries. Since the first nuclear power plant became active in 1951, there has been a host of accidents associated with nuclear energy that, in the best case scenario, put the local environment at risk—and, at worst, have resulted in hundreds of cases of thyroid cancer. Nuclear energy also relies on exhaustible resources. While wind energy has its own problems—such as birds and bats sometimes getting caught in the turbine and not always being totally efficient—it doesn’t approach the risk posed by nuclear energy.
How does burning fossil fuels affect the environment?
Burning fossil fuels releases a greenhouse gas called CO2 and traps heat inside the atmosphere and causes a worldwide increase in temperature, which results in severe and long-lasting damage to human societies and ecosystems. Such high and steady release of CO2, according to NASA’s website, has already impacted weather patterns and will result in increasingly stronger hurricanes, longer and more powerful droughts, and changing sea levels (which are expected rise 1-4 feet over the next hundred years). We can also expect the average global temperature to increase from anywhere between 2.5-10 degrees Fahrenheit in the coming decades—and the state of the earth’s ecosystem is only going to get increasingly more out of control without strong steps taken towards using safer and more responsible electricity production.
What are the benefits of wind energy?
The most obvious benefit of the expansion of wind energy is that it replaces many notably harmful ways of harvesting power that have done often, irreversible damage to the environment.

Why do hydroelectric dams affect the environment?
Because the hydroelectric dams control water flow, the water downriver can become stagnant and filled with plant life that can overrun the ecosystem and rot, producing carbon dioxide. Dams also carry the risk of altering fish habitat and passages, changing the quality or temperature of the water, and displacing local aquatic populations.
How does wind power affect land use?
The land use impact of wind power facilities varies substantially depending on the site: wind turbines placed in flat areas typically use more land than those located in hilly areas. However, wind turbines do not occupy all of this land; they must be spaced approximately 5 to 10 rotor diameters apart (a rotor diameter is the diameter of the wind turbine blades). Thus, the turbines themselves and the surrounding infrastructure (including roads and transmission lines) occupy a small portion of the total area of a wind facility.
How much land is used for wind turbines?
A survey by the National Renewable Energy Laboratory of large wind facilities in the United States found that they use between 30 and 141 acres per megawatt of power output capacity (a typical new utility-scale wind turbine is about 2 megawatts). However, less than 1 acre per megawatt is disturbed permanently and less than 3.5 acres per megawatt are disturbed temporarily during construction [ 1 ]. The remainder of the land can be used for a variety of other productive purposes, including livestock grazing, agriculture, highways, and hiking trails [ 2 ]. Alternatively, wind facilities can be sited on brownfields (abandoned or underused industrial land) or other commercial and industrial locations, which significantly reduces concerns about land use [ 3 ].
Why do offshore wind turbines require more space?
Offshore wind facilities require larger amounts of space because the turbines and blades are bigger than their land-based counterparts. Depending on their location, such offshore installations may compete with a variety of other ocean activities, such as fishing, recreational activities, sand and gravel extraction, oil and gas extraction, navigation, and aquaculture. Employing best practices in planning and siting can help minimize potential land use impacts of offshore and land-based wind projects [ 4 ].
How do wind turbines affect wildlife?

Why are cost reductions happening?
There are three reasons for the cost reductions. First, turbines are becoming larger, with taller towers, and lighter construction. Second, increased efficiency in the supply chain and manufacturing systems are lowering cost.
How does wind compete with fossil fuels?
I asked how effectively wind can compete with fossil fuel sources, and learned that wind has become extremely cost effective. In areas where energy consumption is increasing so that new power sources have to be built, there is a basic parity and in many cases, wind wins on cost alone. In mature markets where existing coal, nuclear, or gas power generation infrastructure is already built (often with years of subsidies), it is more challenging to build wind because new infrastructure would have to be created. There, new-build wind has to compete with the costs of maintenance of the existing energy source. However, even then, wind is an attractive option, aside from the fact it creates energy without greenhouse gas emissions.
Why is the grid more stable?
Importantly, there is better interconnection with neighboring countries and linking with storage or hydropower sources, which also increases reliability and efficiency.
1. Noise pollution
Though commercial wind farms are typically located far away from human habitation, there are instances where people living in the vicinity of wind farms are affected by the sound wind turbines produce when their blades turn, making a “whooshing” sound. The generator kept within the wind turbine also generates a humming sound as it does its work.
2. Threat to wildlife
Wind turbines are known to disrupt wildlife in multiple ways. Wherever commercial wind farms are located, the birds have a hard time surviving. Whether small or big, birds stand a slim chance of surviving a direct hit with the turbine blades. And with so many turbines located in the area, it is no wonder that the population of birds goes down.
3. Affects local weather
As the blades of the turbines turn to generate electricity, it also has inadvertent consequences. It creates a disturbance in the air that can have far-reaching effects on the environment. The turbulence created by wind turbines is known to warm up the surface temperature at night and cool it down during the day.
4. Safety issues at sea
Setting up offshore wind turbines at sea may be a solution to reduce its negative impact on humans and wildlife on the land. However, it can disrupt the lives and habitat of sea creatures. During the construction as well as during the operational phase, offshore wind farms destroy and unsettle marine habitats.
5. Far off location
Typically, wind farms are located far away from cities and towns. Intentionally, remote locations are chosen for setting up wind farms so that large-scale land acquisition is possible. However, this means paving new roads and transporting the machinery and construction material to the site.
6. Aesthetic impact
Large-scale wind farms are often seen as signs of progress. However, these farms rob the land of its natural greenery and beauty. Though the land can be used for cultivation, the forests destroyed for setting up the wind farm are lost forever.
7. Carbon footprint of turbines
The manufacture of wind turbines needs metals and other materials. The production of these raw materials as well as the manufacturing process are often run using fossil fuels. After manufacture, the turbines need to be transported to the location of the wind farms.
