Alternative energy is often called energy from a source other than the conventional fossil fuel source like oil, natural gas & coal. Alternative energy is not popularly used & is usually environmentally sound. It is also sometimes renewable energy. Several alternative energy sources are solar, wind, biomass, wave & tidal energy.

They are currently reliant on fossil fuel & other non-renewable energy. This causes great harm to out environment & will also tremendously affect future generations. Most of the current population relies on non-renewable energy source such as oil, natural gas, fossil fuel & coal.
Fossil fuels are non-renewable source of energy, it means it could run out. Also, when fossil fuels are burnt they produce the gas carbon dioxide (CO2). Carbon dioxide is known as a greenhouse gas since it traps heat from the sun & preventing it from escaping out of the Earth's atmosphere in to space. The amount of greenhouse gasses in the atmosphere is increasing. It leads to rising Earth temperature called global warming.
There's several countries that are providing incentives for private sector or personal efforts to use renewable energy by giving tax incentives & subsidies. Currently, 1

Alternative & renewable source of energy is therefore a necessity. Renewable energy is derived from resources that are regenerative or regenerate after consumption. For this reason, renewable energy unlike fossil fuels do not produce as lots of greenhouse gases.
Solar energy come from the sun's rays that reach the Earth. Solar energy can be converted in to heat & electricity. Solar energy can be converted to thermal or energy generated from heat. It can be used to heat water & heat spaces like inside greenhouses, homes & other buildings.
Several sources of renewable or also called alternative energy are sunlight, wind, rain, tides & geothermal heat. Wind energy comes from wind power that is generated from wind turbines. Wind energy are non-polluting energy source with low maintenance cost although the initial expense may be high.
Meanwhile, hydropower makes use of the energy the water gains when it drops in elevation. That is why hydropower plants are near waterfalls or dams. Hydropower has been used since the start of the electric age but unfortunately the value of this energy has not yet been developed & maximized.

Biomass energy comes from plants & animal material that are usable source of energy like wood from trees, waste from other plants, manure or animal wastes. Biomass energy has numerous benefits. It uses waste materials that are usually dumped & uses up methane gas (a greenhouse gas). Fuels like ethanol can be made from biomass & uses as an alternative to petrol.
These only show that they can pick alternative ways on using energy to lessesn its negative impact on our environment. Alternative energy sources provide us a choice for a bright & healthy future. It may something be out of the ordinary but it can also be useful
Another alternative energy source would be geothermal energy or energy derived from the underwater heat the world is emitting. Geothermal power plants are unaffected of changing weather conditions. It is also price competitive & helps the people's reliance on fossil fuels diminish.

I'm just a concerned middle aged American. I can't see the Power Companies keep raising my power bill every year. So I'm working with this company green power easy to eliminate my power bill, " to get off the grid".
