Solar energy is a natural form of renewable energy that comes from the sun. Solar energy can be used in the form of electrical power or heat. Learning about solar power, how it works and how it can be used is one step towards implementing this healthy and sustainable power source into our world.

Solar Power - How it Works

The sun releases energy naturally through both light rays and heat. It is a renewable energy source because we will not run out of solar energy like we will one day run out of the oil or coal that we currently use as our energy sources.

There are some challenges to using solar energy. While it is plentiful, it is not consistent. You know for yourself that some days there is a lot of sun, but other days there is little sun. Harnessing and storing solar energy can be expensive, but the good news is that it is getting cheaper and becoming more affordable for the average person to be able to use solar energy.

How is Solar Energy Used?

Solar energy has been used since the beginning of time by humans, animals and nature. Think about how we use the sun everyday. We use it as a light source and in the summer months, it serves as a heat source, too. Animals use it the same way. For plants the sun provides the energy necessary for them to grow and reproduce. The sun heats the waters and it helps movement of wind.

Technology has now made it possible for you to use solar energy in your own home, both to power appliances and gadgets, and also to serve as your main energy source. Solar panels capture the solar energy and store the energy so that it can be used to power your home. Solar energy can also be used to heat water instead of using a traditional water heater.

Types of Solar Energy

There are two types of solar energy that are used in residential and commercial settings. These are passive and active solar energy.

Passive energy is the raw energy that comes directly from the sun. It can be used in its natural state as light and heat. It can be used to heat or cool a home and in this state it is used in the plant process of photosynthesis.

Active solar energy is captured and stored energy. This allows it to be used in many different applications. Active solar can operate generators, engines, panels, appliances and gadgets that are designed to use solar energy.

The Future of Solar Energy

Solar energy has been a rather slow growing power source. This has mostly been due to the costs associated with manufacturing the solar panels needed to help make solar energy useful in homes and businesses. The good news is, costs are going down now and technology is advancing to help make solar energy a more viable and useable energy source.

With the depletion of fossil fuels and other non-renewable energy sources, there is a need for new sustainable and renewable energy technologies. Solar energy is so plentiful and useful that it definitely has a place in the future to be one of our top energy sources.
