Alternative energy is any energy source that does not use fossil fuels (coal, gasoline and natural gas). Renewable energy comes from natural sources that don’t run out. The alternative energies that are already being used are solar, wind, geothermal, hydroelectric, tidal, biomass and hydrogen.

What is a simple definition of alternative energy?

Alternative Energy refers to energy sources other than fossil fuels. This includes all renewable sources and nuclear. A renewable energy source is produced from sources that do not deplete or can be replenished ¹ within a human’s lifetime.

What is alternative energy quizlet?

alternative energy source. an energy source that does not use fossil fuels. examples are wind, hydroelectric, and solar energy. hydroelectric. electricity generated by moving water.

What is the most alternative energy?

Hydropower is the most widely-used renewable power source, with the global hydroelectric installed capacity exceeding 1,295GW, accounting for more than 18% of the world’s total installed power generation capacity and more than 54% of the global renewable power generation capacity.

What’s an example of alternative energy?

The most popular renewable energy sources currently are: Wind energy. Hydro energy. Tidal energy. Geothermal energy.

What is alternative energy class 10?

Renewable energy is an energy that is produced from natural processes and continuously replenished. Few examples of renewable energy are sunlight, water, wind, tides, geothermal heat, and biomass.

What do you mean by alternative?

1: a proposition or situation offering a choice between two or more things only one of which may be chosen. 2a: one of two or more things, courses, or propositions to be chosen. b: something which can be chosen instead. in the alternative.

What is the need for developing alternative sources of energy?

Renewable energy can play an important role in U.S. energy security and in reducing greenhouse gas emissions. Using renewable energy can help to reduce energy imports and reduce fossil fuel use, which is the largest source of U.S. carbon dioxide emissions.

Which the energy source is most renewable quizlet?

Hydroelectric power is the most widely used source of renewable energy.

What is the most efficient alternative energy source?

Wind power efficiency Wind power is the leading renewable energy source, bringing in 8% of the energy of the United States. This renewable energy source isn’t as quiet as solar power, but it does pack a solid efficiency rating and is generally environmentally friendly.

What is the best energy?

Nuclear Has The Highest Capacity Factor As you can see, nuclear energy has by far the highest capacity factor of any other energy source. This basically means nuclear power plants are producing maximum power more than 93% of the time during the year.

What is an advantage to alternative energy technology?

One of the main advantages of alternative energy technology is that people can meet their basic needs and more while also benefitting their environment. By implementing sustainable solutions to challenges, communities develop more opportunities to design healthier livelihoods.

What is alternative energy and what are some examples?

Examples of alternative energy sources besides fossil fuels (coal, natural gas, oil) could include harnessing the power of the sun (solar), wind, waves (hydro), or the earth itself (geothermal). These energy sources are considered ‘renewable’ energy sources, as they will not run out.

What is alternative energy and list few examples of alternative energy?

Besides the seven energy sources listed above, other alternative energy sources include geothermal power, wave energy, hydroelectric energy, solar thermal energy and even space solar energy. Geothermal energy is that generated in the earth and harnessed, while wave and hydroelectric energy harness the power of water.

Why should you know about alternative energy resources?

Alternative energy sources have a much lower carbon footprint than natural gas, coal, and other fossil fuels. Switching to renewable energy sources to produce electricity will help the planet by slowing and reversing climate change.
