The 5 Most Popular Natural Energy Sources

Many people have been looking for ways to cut costs and save money while protecting the environment. The poorest people in the world are those who are more affected by the devastating effects of climate change, caused by increased carbon dioxide emissions.

Energy efficiency is one of the most cost effective and easiest methods to combat climate change and clean the air that we breathe. The Department of Energy is even working together with businesses, universities and national laboratories to develop innovative, energy- efficient technologies.

The use of Renewable Energy has been found to be the most efficient ways to help people save power and at the same time reduce the impact on the environment. This is also an important part of the energy revolution that we need in order to curb the shattering climate change. By taking full advantage of our natural resources, saving power usage and using renewable energy, together, we can shape a better world for the future.

By saving power, we are helping the environment. This will not only improve our lives, but will also help make our lives simpler, more enjoyable and happier.

You can always help save the world and you can do this by saving energy. Lessen your carbon emission, enhance the health of the Earth and save the world.

Some clean energy ideas include:  Hydroelectric, Solar, Wind, Geothermal and Hydrogen.

Hydroelectic

This can be traced back to waterwheels for sawmills etc… We see it in action at Sturbridge Village.  This power source basically takes the kinetic energy of water and converts it into electricity and is dependent upon geographic location due to the need for a dependable water source. Approximately 20% of the total power generation in the world is due to Hydro Energy.  In the United States that rate is lower.

Solar

Capturing the energy of sunlight through the use of photovoltaic systems. This energy is stored so when the sun isn’t out – you still have power.  This energy is stored in battery banks.  If you operate solely on solar power you may need to have a generator so you can still have plenty of power even on extended periods of cloudy days.  A generator can resupply your battery bank with energy.  If you are grid-tied then you can still get power on low sun days and you can even sell back energy.  Off the grid – well you are not tied to anything and are totally self reliant. We have photovoltaic panels on top of our schools.

Wind

This is one we have the benefit of at the district I work in.  Technically the wind turbines are not on school property – rather they are across the street and the town allows us access for classroom studies and we even have an energy panel that allows the students to analyze the data.  The premise is simple – as the wind turbine moves with the breeze, it produces energy.  We have all seen the old fashioned wind mills; then came the more updated wind turbines; and now they have even developed micro wind turbines that only result in a 7% loss of energy.

Geothermal

This is another one that school construction programs are moving towards.  It relies on drawing heat from the earth from sources that are close to the surface and this heat is harnessed and turned into energy.

Hydrogen

Hydrogen is a source I am less familiar with but it has a firm foundation in energy sources in the US.  It is high in energy with little or no pollution.  Hydrogen fuel cells convert chemical energy of hydrogen into electricity and the only byproducts are water and heat.
