Why scientist are trying to find alternative energy sources now?

Today, we start using alternative sources of energy like solar power, wind power, geothermal, biomass, hydro power, waste energy and so on, because these renewable energy sources are not polluting the environment and are helping us to reduce the level of greenhouse gas emissions in the atmosphere and to reduce climate …

Why do we need to find renewable energy sources now?

Renewable energy sources eliminate the use of these fuels, which can aid your electricity supplier to reduce its carbon footprint. This could help the environment as it reduces thermal pollution, waste and water consumption that is believed by the science community to be a factor in climate change.

Why are scientists looking for alternative energy sources such as solar and wind power?

Wind, solar, and hydroelectric systems generate electricity with no associated air pollution emissions. Geothermal and biomass systems emit some air pollutants, though total air emissions are generally much lower than those of coal- and natural gas-fired power plants.

What is the best renewable energy source?

What Is the Best Renewable Energy Source?

  • Wind. The largest source of sustainable energy in the United States, wind power is responsible for about 8.4 percent of all energy sources generated in the country. …
  • Sun. Wind and solar power represent the two fastest-growing sources of power in the US. …
  • Water. …
  • Garbage.
GOOD TO KNOW:  Your question: What percent of emissions are from power plants?

How expensive is alternative energy?

Solar cost about 19 cents more per KWH than gas or coal. Wind power is second behind that, and adopting any of the other renewable technologies will be an outrageously expensive undertaking.

Is alternative energy good?

Renewable energy provides reliable power supplies and fuel diversification, which enhance energy security and lower risk of fuel spills while reducing the need for imported fuels. Renewable energy also helps conserve the nation’s natural resources.

What would happen if we ran out of all energy resources could that ever happen?

A new study published today in Science Advances finds that if we burn all of the remaining fossil fuels on Earth, almost all of the ice in Antarctica will melt, potentially causing sea levels to rise by as much as 200 feet–enough to drown most major cities in the world.
