Natural Energy Sources

The three main elements for generating electricity from natural energy sources, come in the form of the sun, wind, and tide.
Other renewable energy sources are geothermal energy, and hydroelectric (which we will not go into on this page.)
All of the above natural energies have advantages and disadvantages, we shall now go into each one.
The use of natural energy sources still has many advantages over the use of fossil fuels, yet the cost of investment can sometimes be too high for most people.
Solar Energy Source
Solar energy is
energy the earth receives from the sun in the form of solar
radiation. We can use this energy source to generate electricity, and
to heat water.
Photons contained within the suns rays, make the production of electricity possible through the use of a solar cell or panel.
The main disadvantage of the use of solar power, is that the panels can be quite expensive, and you usually need more than one solar panel, depending on how much electricity you require.
An advantage of solar electricity devices is the relative ease of installation, and the long term cost effectiveness. This makes solar panels the most common renewable energy source for home owners.
Wind Energy Source
Wind turbines are great for using the winds natural energy source to give a boost to your home power supply.
The problem with renewable wind energy is mainly down to the relatively low output of electricity you could receive.
To get a decent output, you need a large wind turbine, but now you are faced with the problem of noise pollution, and increasing cost.
You should always consider solar energy sources over wind energy sources, if suited to your location.
Tidal Power
An energy source increasing in popularity over recent years is tidal power. This highly renewable energy source has a huge force behind it, and is able to drive water turbines (much like a water mill), around 100 meters out to see as the tides go in and out.
The main problem with this method is the effect it can have towards sea life and the blocking of hipping access to various coastlines.
