Energy Free Off Grid

The great thing about renewable alternative energy sources is that they are found in abundance in nature and their conversion into energy typically has little negative impact on the environment. The “plus” is that they are also GREEN!

What great alternative energy sources these are because their use also preserves the natural resources for other people to use again as sources of energy.  Here are the top 2 popular renewable energy sources.

Solar Energy

The sun will last for many hundreds of generations to come and our ability to gather its energy into solar cells provides us with an unlimited source of readily available green energy.  The sun’s heat is converted into electricity without the use of burning carbon-based fuel such as oil and coal.

Wind Energy

Becoming more popular recently is the tactic to harness wind for energy. This type of power generation goes back to before the 15^th century when ships and windmills used the wind to produce energy. The biggest drawback was the inefficiency of converting this type of alternative energy. With today’s technology the efficiency factor has been multiplied many hundredfold, if not even thousand fold.

The use of windmills throughout history is well documented and they used wind energy to enable the mechanical machinery to perform labour-intensive activities. These activities included pumping of water from wells and crushing grains for food production.

Modern windmills have boosted the efficiency of the original models with the addition of a wind turbine. The wind still turns the blades which now create energy through the turbine to produce electricity. The electricity generated now powers the “machinery” to perform routine everyday tasks.

These are renewable alternative energy sources that will never run out
