Solar Power Electricity - Urged By Governments Globally

Solar power electricity is just one of several methods that are used to produce electrical power. Scientists are convinced that solar energy can potentially supply many, many times the total world energy requirements.

Most of us take the supply of electricity for granted. We are quite contented to simply plug our heaters, cookers, fridges, computers and televisions in to the electric sockets that are situated conveniently in the walls of our homes.

Most people assume that their electric power arrives through the electric grid from a power plant which is situated somewhere not too far from where we live and then pay the utility company for their monthly usage. And this is the end of it.

But there are different types of energy plants generating the electricity that is contributing to the grid for our use. There are hydroelectric power plants that generate electricity by utilizing the power of water, nuclear power plants that harness the energy of the atom, coal power plants that use our ever dwindling fossil fuels and wind farm power plants harnessing the strength of the wind to generate electricity.

These all have the drawback of being costly to build, have high maintenance costs and their fuel costs are exorbitant.

Solar power plants are springing up all over the world as various methods are discovered for harnessing the power of the sun to generate electricity. Governments are pumping countless dollars into solar plants to test devices and materials to enable them to add storage for the electricity that they produce.

solar power electricity falls into the two common categories of terrestrial solar power and space-based solar power.

Solar power panels utilize a photovoltaic cell to convert light into an electric current. This is perhaps the method that we are most familiar with since it is these solar panels that are used for generating electrical power in the home. This method has also been widely used in power plants around the world. There are different types of photovoltaic cells that are being tested and manufactured including thin film, monocrystalline and polychrystalline silicon.

Concentrating solar power is a method of using the suns heat to generate steam that drives an electricity turbine. Mirrors that track the sun are used to focus a large area of sunlight into a compact beam which is then directed at a tower which then heats a liquid in the conventional way. Again different methods and types of mirrors are being tested in this area.

Space-based solar power will use a satellite to collect energy, convert it into electrical power and then transmit it to earth. This is still in the experimental stage but in the not too distant future we are going to be using electricity that has been beamed down to earth by wireless power transmission with a microwave beam. There are many arguments for using a space based solar system rather than a terrestrial not least because they would be not dependent on varying weather conditions.

Governments are investing heavily in solar power plants as an alternate method of generating electricity. They are pumping huge sums of money into the development of finding improved techniques for storing the electricity.

This might all seem to be taking place on a rather grand scale where we see a solar power plant with many acres of mirrors and solar panels gathering and directing the suns heat to generate power. But at the same time governments around the world are offering a selection of grants, tax rebates and other incentives to homeowners who would like to build their own small scale solar power electricity systems. In many situations it can be quite possible to sell any excess electricity that you are able to generate back to the utility company.
