Which Energy Source Contributes Least To Global Warming Answers Com

Global warming is an urgent issue facing humanity today and the need to determine the least polluting energy sources is a priority. There are several energy sources that are used to generate electricity and power our lives, but which are the least harmful? According to Answers.com, the energy sources that contribute least to global warming are solar, wind, hydro and nuclear power.

Solar energy is quickly becoming one of the most popular renewable energy sources due to its abundance and cost-effectiveness. Solar energy is a clean and renewable source of energy; it does not release any harmful gases into the atmosphere when used. Solar panels are easily installed, require almost no maintenance and can be used to generate electricity in homes, businesses and even on the roads. Solar energy is also a completely free energy source and does not cause any air or water pollution. The only downside to solar energy is that it is intermittent, meaning that the sun needs to be shining for it to be effective.

Wind energy is one of the most efficient and powerful renewable energy sources. It produces minimal environmental damage and does not require any fuel apart from the wind itself. Wind turbines can be used to generate electricity and are generally placed in locations where there is a consistent supply of wind. Wind energy creates much less noise pollution than conventional energy sources and is relatively cost-effective. One of the main drawbacks of wind energy is the aesthetics; the tall and imposing turbines may not be aesthetically pleasing to everyone.

Hydropower is a renewable energy source that generates electricity by using the power of water. It is a relatively clean energy source that emits a relatively small amount of carbon dioxide into the atmosphere. Hydropower is incredibly reliable, as it is powered by a renewable source that never runs out, and it is one of the most cost-effective sources of renewable energy. However, hydropower does have some drawbacks, such as the disruption to aquatic ecosystems and the displacing of people living in valleys that are flooded to create reservoirs.

Nuclear power is another energy source that has recently become more popular as a result of increased focus on reducing carbon emissions. Nuclear power produces very little in terms of carbon dioxide and other greenhouse gases, and is generally very safe to use. However, there are some potential risks with nuclear power, such as potential radiation leaks, the possibility of proliferation, and the difficulty of disposing nuclear waste. It is also a very expensive energy source and can take a long time to set up.

In conclusion, it is clear that the energy source that is least harmful to the environment is solar energy, followed closely by wind, then hydropower, and finally nuclear power. All of these energy sources have both pros and cons when it comes to their environmental impact. It is important for society to continue researching the most efficient and least polluting energy sources, in order to ensure our planet is kept sustainable for future generations.
