As our plane down swiftly to an impending energy crisis, we need to end our dependence on fossil fuels and non-renewable energy sources as quickly as possible. As the name suggests, non-renewable energy sources can not be replaced, and when used, are gone forever. Renewable energy sources, compared never runs dry. The three main sources of renewable energy solutions, solar energy, hydropower and wind energy. But what are they and how can we benefit from them?
Solar energy: the energy from sun is the most abundant energy source available on Earth. Not only is it free in most parts of the world, it is also extremely plentiful. Where possible we should make use of this incredible free source of energy. There are many solar energy solutions available today that you can easily apply at home. Not only will this help you cut down on energy bills, but you will also be contributing to a greener, cleaner world. . Solar power solutions comprise of solar cookers, solar heating, solar lighting systems, solar dryers etc.
Besides being very cost effective and environmentally friendly, solar energy systems have many other benefits. They are low maintenance, saving time and effort. You can also get a very good return on your investment in a short timeframe. This means that after a short time, the system will have paid for itself, and will continue to provide completely free energy for a long time thereafter.
Hydro – electric power: Hydro-electric or water, electrical energy is a highly efficient renewable energy source. Even generally produced on an industrial scale, small hydroelectric generator is now available so you can take advantage of this renewable source. It has been estimated that 90 percent of the electrical energy produced by renewable energy is produced solely by hydro power. With large hydro schemes dams are built to help generate electricity by creating a water column that when released, unleashes an enormous amount of energy can be converted into electricity by large wind turbines.
There have been some concerns about using this hydropower because large plants can destroy large areas of natural habitats as they are handed over to the lakes.
Wind Energy: Windmills have been used for thousands of years for a variety of uses. They helped tow boats and pump water and grind grain to make flour. Finally in more modern times they were a source for generating electricity.
Wind turbines, both large and small has proven to be highly effective to produce large quantities of cheap electricity. When applied to a smaller home-based scale, they can actually very often completely replace conventional energy sources. An excellent source of renewable energy, wind energy will go a long way in promising a good future for coming generations.
