What are pros and cons of renewable energy?

Pros: It is abundant, and can be used without interruption, cleaner than fossil fuel. Cons: Can result in air pollution, takes a lot of energy to produce, can be seasonable and competes with food production. Landfill gas, solid waste energy comes from harnessing the decomposition of organic material.

Can we rely on renewable energy?

Yes, wind is free. But the process of turning sunlight and wind into useable energy on a mass scale is far from free. In fact, compared to the other sources of energy — fossil fuels, nuclear power, and hydroelectric power, solar and wind power are very expensive.

What renewable energy is the most efficient?

The most efficient forms of renewable energy geothermal, solar, wind, hydroelectricity and biomass. Biomass has the biggest contribution with 50%, followed by hydroelectricity at 26% and wind power at 18%.
