renewable energy sources – we can change things?
Unlike fossil fuels like oil, gas and electricity produced from burning coal, renewable energy is not exhausted.
Therefore, it is logical to consider any changes to the system as soon as possible to reduce our carbon footprint, help save money and repair the concern that the global warming and environmental damage can be irrevocable.
Renewable energy sources are natural resources including energy from sunlight, wind, water, geothermal heat and biomass energy (Wood energy, waste, hydrogen and alcohol such as ethanol).
In 2008, approximately 19% of energy consumption came from renewable sources, with 13% coming specifically from traditional biomass. It is mainly used for heating purposes and electricity generation.
One area of growth are now called "new renewables" such systems and small hydro, biomass, Wind, solar, geothermal and biofuels. New programs such as the United Kingdom "feed" rate that makes people to produce electricity Renewable focused more attention recently in the use of renewable energy sources. People can get a fixed income for each kilowatt hour of electricity produced and used on your property (production rate) and earn a stable income for each kilowatt-hour of overtime electricity produced and sold to the network (export tax)
Overall, about 3 million households get the power small solar photovoltaic systems.
Solar water heater
The collection of billions of kJ of energy received from the sun each day (solar energy) can be used to heat a fluid such as water in the solar collectors. These are mainly flat collector panels that are defined in the buildings south roof or walls with lids to admit sunlight.
Black channels or pipes inside the panels easily absorb heat and transfer the water circulating around these internal mechanisms, hot water is pumped in a heat exchanger that extracts heat for indoor use. Thermal solar panels can produce 60% of hot water needs.
Systems solar photovoltaic
Solar energy can generate electricity by converting the Sun's radiation into electricity by specialized cells mounted photovoltaic (PV). Solar electricity production depends on light intensity and not in direct sunlight or heat, so it works even on cloudy days throughout the year.
today's devices PV convert 7% -17% of light energy into electrical energy, which will increase as new systems are developed and the market.
Benefits of Solar Energy Technology
- Sunlight is free and help reduce costs in hot water and electricity.
- Throughout the year, the solar panels can provide 60% water national property hot (ECS) requirements.
- Production of hot water from solar panels can be easily integrated radiant floor heating.
