Image via Wikipedia Alternative energy is basically any type of useful energy that does not rely on conventional fossil fuels, technically alternative energies do not have to be renewable but “alternative” and “renewable” or “sustainable” in common usage are interchangeable. When it comes to renewable energy, it is important for two reasons. You will find that there is lot that is hurting the environment. You will find that there is a lot of future harm from the greenhouse effect and effects caused by the fossil fuels. Renewable forms of energy are typically safe for the earth, making them a much cleaner option. Second, renewable energy sources are exactly what their name implies—renewable. Therefore, these sources of energy will not run out or become scarce and expensive, as fossil fuels will in the near future. Because the renewable energy sources are becoming more and more researched, it is only a matter of time when major energy companies begin their switch from fossil fuels to these alternative energies.

There are many different types of renewable energy, including solar, wind, water, geothermal, biomass, and tidal. Many effects will have a positive outlook on the environment because there is nothing produced by the energies that could harm the environment at all. Solar energy refers to power from the sun. We see this in everyday life as solar covers are placed on swimming pools to help then gather and retain heat. When you wear black on a sunny day, you will feel the effects of solar power. Solar power takes this heat and turns it into useful energy, which we can use to heat our homes and power other electronic devices. Wind energy is one of the oldest forms of alternative energy, along with water power, Windmills and waterwheels were used as early as the middle ages to produce energy, and are still being used in many countries today in refined forms. By using generators, you will be able to convert power into electricity by using things like generators, windmills, waterwheels, and other old-world technologies. Geothermal energy taps into the heat from the earth, by using geological hotspots such as volcanic sites, to produce energy. Biomass is also a very earth-like way of producing heat. This form of renewable energy refers to the use of once living organisms to produce heat and other forms of energy. Tidal waves can begin to make the energy or power that waterwheels and windmills in the same way. The ocean can also be used for its heated surface temperatures and cool deep-water temperatures to convert heat energy into useful electricity.

Image via Wikipedia Unfortunately, the reality didn’t quite match up with the dream. Solar power cells were ( and still are) expensive to manufacture, and unless you had a lot of panels exposed to a lot of sunlight, solar power systems didn’t produce very much power. However, now that we’re seeing more refinement and advancements in solar power technology, along with growing popularity of renewable energy systems we may be witnessing a rebirth in solar power systems, at least in certain environments.

Solar PV (photovoltaic) uses energy from the sun to create electricity to run appliances and lighting. PV requires only daylight - not direct sunlight - to generate electricity.
