Renewable energy systems - Everything you need to know

With the rapid decrease in the supply of conventional energy sources such as those that come from fossil fuels, it has not been a wonder that more and more people are making use of renewable energy systems in order to keep up with their needs. These are types of energy systems that are harnessed from nature. This means that they are constantly replenished and has the possibility of never ever running out. These characteristics have made them even more desirable as compared to that of conventional energy sources.

As is said earlier, renewable energy systems get their energy from nature. The most common of these natural sources include the sun, water, wind, and geothermal. The current state of science and technology has even enabled man to harness energy from waste materials. This has led to a bigger supply of energy that will be able to accommodate the growing needs of the world in the years to come.

Since the Planning and Energy Act came into force in 2008, local authorities have the power to require that development proposals will meet ambitious energy performance standards. Firstly they can require that the energy performance of buildings is greater than that required by the building regulations. Furthermore the planning authority may require that a proportion of the energy that is used by the new development will be produced on the development site by using renewable sources. Many local authorities have now adopted policies that require that a certain percentage of the energy use of new development will be generated on the site using low or zero carbon technologies. A description of the selected mix of technologies and the rational behind them is laid down in an Energy Statement.

Some development proposals could use "Renewables Obligation Certificates" to part fund the additional cost of providing renewable energy. For the majority of development projects, however, the requirement to provide on-site renewable energy only adds to the cost. The UK Renewable Energy Strategy and the UK Low Carbon Transition plan introduce a "clean energy cash-back" system for energy generating plant with an installed capacity of up to 5MW. Two schemes that are currently proposed are the "Renewable Heat Incentive" which will be available from April 2011 and the "Feed-in Tariffs" (FITs) for the generation of small scale electricity, which will be available from April 2010. The FITs will be available for both small-scale community facilities and installations that serve only one unit. Implementation of the scheme will mean a higher return on electricity that is fed back into the grid than under the current arrangements.

Aside from the first two, renewable energy can also be derived from the wind through the use of wind farms. It uses the same principle found in hydroelectric dams to convert the wind energy to kinetic energy and then to electricity. Geothermal power is also a good form of renewable energy system. This, on the other hand, makes use of the heat from deep inside the earth to produce electricity. Various methods are used to do this like harnessing the steam that naturally comes out of fissures on the ground.

As a renewable energy resource, a marine solar power system is a very practical choice. It maintains a floating charge on your battery bank(s) while on mooring and allows you to use most if not all your modern conveniences while at anchor
