Uses of Solar Energy

Solar Energy Uses

We have always used solar energy as far back as humans have existed on this planet. We know today, that there are multiple uses of solar energy. We use the solar energy every day in many different ways. When we hang laundry outside to dry in the sun, we are using the solar heat to do work, drying our clothes. Plants use the solar light to make food. Animals eat plants for food. And as we learned, decaying plants hundreds of millions of years ago produced the coal, oil and natural gas that we use today.


History of Solar Energy

Solar Hot Water
Solar Thermal Electricity
Solar Cells or Photovoltaic Energy

Very often there is confusion about the various methods used to harness solar energy.Energy from the sun can be categorized in two ways: (1) in the form of heat (or thermal energy), and (2) in the form of light energy. Solar thermal technologies uses the solar heat energy to heat substances (such as water or air) for applications such as space heating, pool heating and water heating for homes and businesses. There are a variety of products on the market that uses solar thermal energy. Often the products used for this application are called solar thermal collectors and can be mounted on the roof of a building or in some other sunny location. The solar heat can also be used to produce electricity on a large utility-scale by converting the solar energy intomechanical energy.

So, fossil fuels is actually solar energy stored millions and millions of years ago. Indirectly, the sun or other are responsible for all our energy. Even nuclear energy comes from a star because the uranium atomsused in nuclear energy were created in the fury of a nova - a star exploding. Let's look at ways in which we can use the solar energy.
