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?
Definition of alternative energy
: usable power (such as heat or electricity) that comes from a renewable or green resource alternative energy sources/technology.
What best describes an alternative energy?
Alternative energy refers to energy sources other than fossil fuels (such as coal, petroleum, and diesel) and includes all renewable and nuclear energy sources.
What is the scientific 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 an alternative energy system?
A renewable energy system can be used to supply some or all of your electricity needs, using technologies like: Small solar electric systems. Small wind electric systems. Microhydropower systems. Small hybrid electric systems (solar and wind).
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 alternative energy and why do we need it?
Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels. Creating economic development and jobs in manufacturing, installation, and more.
What are some examples of alternative energy?
Here are some examples of Alternative Energy Sources and Their Importance
- Hydrogen Gas.
- Tidal Energy.
- Biomass Energy.
- Wind Energy.
- Geothermal Power.
- Natural Gas.
- Wave Energy.
Why is alternative energy important?
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.
What Does alternative energy mean apex?
Alternative energy, by definition, is any source of energy that doesn’t use fossil fuels.
What was the first alternative energy?
1. William Armstrong — hydroelectric power. Water power was hugely important in the early history of electricity generation — the first hydroelectric scheme sparked into life in 1878, a full six years before the modern steam turbine was invented.
Is alternative energy the same as renewable energy?
Renewable energy is energy generated from natural resources—such as sunlight, wind, rain, tides and geothermal heat. Renewable energy is energy that is generated from natural processes that are continuously replenished. … Alternative energy is a term used for an energy source that is an alternative to using fossil fuels.

- Anaerobic Lactic (Glycolytic) Energy System (High to Medium Intensity – Uptempo) …
- Aerobic Energy System (Low Intensity – Long Duration – Endurance)
What is the best energy resources for you why?
Why are renewables a better source? The energy from wind and solar is able to be used and reused without requirement of an exhaustible element. Beyond the source is the product after electricity is produced. The waste of coal or natural gas requires environmental mitigation and an excess of energy.
