Your question: Which alternative energy source do you think is more efficient Why?

What is the most efficient alternative energy source?

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%. Geothermal energy is generated by harnessing the Earth’s natural heat.

What kind of energy sources is the most efficient?

Often ranked as one of the most efficient energy sources, wind energy is harnessed all over the world. Of course, some spots are known as being windier than others, and companies typically make use of these spots by building wind farms filled with turbines there. Wind energy has also been used for hundreds of years.

Is alternative energy more efficient?

When it comes to energy efficiency, renewable energy is generally more efficient than non-renewable energy. The energy we get from wind, the sun, and hydro turbines can be reused without relying on an exhaustible or finite element. … Non-renewable energy sources result in the waste of coal or natural gas.

What is the cleanest energy?

Out of all energy resources, we consider green power (solar, wind, biomass and geothermal) as the cleanest form of energy. So, if we were looking at clean energy on a spectrum, these would be farthest from “dirty” or emissions-heavy energy.

Why do energy sources not have 100% efficiency?

Part of the energy input is wasted. It is used to increase the entropy of the surroundings. Therefore, the useful energy output is necessarily smaller than the energy input. In other words, the efficiency of a heat engine is always less than 100%.
