Around the world renewable energy use is on the rise and these alternative energy sources could hold the key to combating climate change. What is renewable energy?

Renewable energy is generated from sources that naturally replenish themselves and never run out. The most common sources are solar, wind, hydro, geothermal and biomass. Over 80% of the total energy consumed by humans is derived from fossil fuels. However, renewables are the fastest-growing source of energy in the world

Renewable energy has many benefits. First, it can combat climate change because it creates no direct greenhouse gas emissions. The only emissions that they produce are indirect meaning those that result from manufacturing parts installation operation and maintenance but even those are minimal.

Second renewable energy can decrease pollution and therefore reduce threats to our health. Wind, solar and hydroelectric systems create no air pollution emissions and geothermal and biomass energy systems emissions are much lower than non-renewable energy sources.

Third renewable energy is a reliable source of power because renewable energy sources are well renewable they will never run out. Once built renewable facilities cost fairly little to operate and the fuel is often free. As a result, renewable energy prices tend to be stable over time.

While renewable energy has many advantages it is not without downsides. It is difficult for renewable energy sources to generate power on the same large scale as fossil fuels. Building wind farms and dams can disrupt the wildlife and migration patterns and lead to ecological destruction.

Both solar and wind energy are intermittent they only generate power while the sun is shining or while the wind is blowing. Batteries can store excess energy for later use however they are often costly. 

While renewable energy presents some challenges it also offers an environmentally friendly alternative to the greenhouse gas emissions and pollution of fossil fuels and as advances in technology make renewable energy more accessible affordable and efficient an end to climate change could be within our reach.

There is a politician in your state or country, running for an elected position. He has promised to re-open coal mines and stop investments in renewable sources of energy. What’s more, he does not believe in global warming. Write him a letter expressing your opinion on this matter.
