There are several forms of alternative energy that can be used for resources. They aren’t harsh on the environment like fossil fuels. They aren’t going to be used up and depleted either, which is why the use of alternative energy is often promoted.

Solar Power

The most common type of alternative energy that is promoted is solar energy. This is energy that is collected through panels. The sunlight is able to be converted into energy that can be used for electricity, heating, and more. Being able to reduce the amount of heat and electricity used in a home or business adds up quickly.

Hydro Electric Power

Water can also be used to generate alternative energy, known as hydroelectric power. This comes from a turbine and generate that are in a dam. There is pressure created that makes the turbine move and that is how the energy is created, and then processed by a generator. One benefit of this type of resource is that the amount of water can be controlled. That control isn’t in place when you refer to the solar energy or to wind energy.

Biofuels

There are fuels made by plants and animals, called biofuels. This includes wood and methane. The use of ethanol as a type of alternative energy has become increasingly common. It is frequently used in transportation by mixing it with gasoline. It can also be used for cooking and heating.



Natural Gas

Even though natural gas is a fossil fuel, it doesn’t harm the environment as it doesn’t release carbon dioxide. There is a huge amount of natural gas on Earth so there aren’t the same concerns as with other non-renewable types of energy out there. Natural gas used for energy mainly consists of methane. Extensive filtering is part of the process that removes the other elements.

Geothermal Energy

Natural energy that comes from the Earth is called geothermal energy. This stems from rocks that are extremely hot found by drilling into the Earth. The heat of the rocks creates steam that causes turbines to turn. This in turn will power electric generators in a manner that is very self-sufficient.

Wind Power

Another of the more common forms of alternative energy is wind power. This involves tall turbines in the open with three large blades. The wind causes the blades to turn at different speeds. The rotations are what create the electrical current for a generator to convert into a source of power.

Hydrogen

One of the lesser known and infrequently used types of alternative energy is hydrogen. This is because it takes much more energy to make it than it produces so it isn’t a viable large scale solution at this time. One of the benefits though is it does offer a good environmentally safe type of fuel for vehicles. It could prove to be a promising alternative if better methods for creating it can be developed through technology.

Nuclear Energy

Atoms are at the core of the nuclear energy that is created. By splitting or merging these atoms, energy is created. This method can create a large volume of alternative energy but it can also be dangerous. The waste it creates can be difficult to dispose of without creating serious harm for the environment.

Conclusion

There are pros and cons for using any of these types of alternative energy. Some of the are better for the environment than others. Some of them are expensive to implement or unpredictable in terms of how much energy they can create. Yet the fact that we do have plenty of choices that prevent the complete loss of non-renewable resources is very encouraging.
