Renewable
energy sources such as biomass, hydro, geothermal, wind and solar power
supply 8% of the energy used in countries such as Germany, the United
States, Spain and the United Kingdom. Most renewable energy goes into the production of electricity.
The use of renewable energy is not new. More than 150 years ago, wood, which is a form of biomass, up to 90% of our energy needs supplied. As the use of coal, oil and natural gas, we have expanded less dependent on wood as an energy source. Today we are pleased again to renewable sources, new ways to use them to meet our energy needs to find needs.
The demand for renewable energy is driven primarily by the price of the alternatives, namely coal and natural gas (for electricity) and oil (liquid fuel). All the factors that drive from rising oil prices or fears of peak oil, therefore the demand for renewable energy. On the demand side of the equation, significantly increasing global energy demand also plays a major role.
In the past, renewable energy has generally been more expensive to produce and use than fossil fuels. Renewable resources are often in remote areas, and it is expensive to the cities, where the electricity they needed to build power lines. The use of renewable energy is also limited by the fact that they are not always available - cloudy days reduce solar power, wind power and quiet days reduce droughts reduce the water available for hydropower.
The main types of renewable energy are hydropower, biomass (organic matter), geothermal energy, solar energy, wind energy and biofuels. The most commonly used form of renewable energy is traditional biomass, such as burning wood. The market for many forms of renewable energy grows with the conservation of water and energy the main reasons for using these technologies.
Understanding solar solar thermal or solar hot water, uses the energy from the sun to your hot water heat while solar power systems or photovoltaics (PV for short), you can power your household items - like your dishwasher or TV by converting sunlight into electricity.
The cost of the set in a solar system is not much different than installing PV. Thermal solar panels cost about the same as PV modules per unit, and the balance of the system and the labor market is generally comparable in price.
The difference lies in the effectiveness. Thermal panels on average about 40 square meters, compared with 15 for the PV collector. This means you get almost 2 ½ tome solar energy coming in. Plus, the thermal panel converts more than 50% of this energy into heat, while a good PV panel not much more than 15%.
The only problem with solar PV is that the photovoltaic cells become less efficient as they get hotter, a decline, which may be extensive on hot sunny days. Furthermore some energy is inefficient and PV "lost" to the environment.
The financial benefits are such good people choose to Photovoltaic (PV) systems as an alternative to invest their money in a bank or building society (which are taxable) install.
