Why do scientists find alternative energy sources?
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 is it important to find alternative forms of energy?
If we continue to use fossil fuels, we may increase the temperature of the planet in ways that will harm us and our entire ecosystem. … They will eventually run out, even as the population of Earth grows. For both these reasons, we need to find other sources of energy that do not emit carbon dioxide when used.

What are the 2 forms of energy?
After hundreds of years of observation and experimentation, science has classified energy into two main forms: kinetic energy and potential energy. In addition, potential energy takes several forms of its own. Kinetic energy is defined as the energy of a moving object.
Do we need alternative energy?
Using more renewable energy can lower the prices of and demand for natural gas and coal by increasing competition and diversifying our energy supplies. And an increased reliance on renewable energy can help protect consumers when fossil fuel prices spike.
Which renewable energy is used most to generate electricity?
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 are the major sources of energy?
There are five major renewable energy sources
- Solar energy from the sun.
- Geothermal energy from heat inside the earth.
- Wind energy.
- Biomass from plants.
- Hydropower from flowing water.
What is the cheapest alternative energy source?
Hydroelectric power is currently the cheapest renewable energy source, costing $0.05 per kilowatt-hour on average 2. Hydroelectric power is the cheapest because the infrastructure has been in place for a long time, and it produces electricity consistently.
