Various Solar Energy Facts
renewable sources like oil, gas and coal is increasing at an alarming rate. The time has finally come to look after some other renewable sources of energy, i.e., solar, wind and geothermal energy. Although many countries have started utilizing solar energy extensively, they still have to go a long way to exploit this renewable energy to fulfill their daily demand for energy.
With all the growing concerns about sustainable development all across the globe, the solar energy industry is bound to become a booming industry in a few years' time. It will not only create several job openings for people but also it would help us in our eco-friendly survival as well.
It is no surprise that everyone is looking for some alternative energy source that would help them conserve the non renewable resources a little better for their future generations. Solar energy is definitely the best go-to source of energy for them, and it is undeniably the future of our planet.
What is Solar Energy?
Solar energy refers to energy from the sun. The sun has produced energy for billions of years. It is the most important source of energy for life forms. It is a renewable source of energy, unlike non renewable sources such as fossil fuels. Solar energy technologies use the sun's energy to light homes, produce hot water, heat homes, as shown in solar tankless water heater reviews and electricity.
The main benefit of solare energy is that it does not produce any pollutants and is one of the cleanest sources of energy. It is are renewable source of energy, requires low maintenance and is easy to install. The only limitation that solar energy possesses is that it cannot be used at night, and the amount of sunlight that is received on earth depends on location, time of day, time of year, and weather conditions.
Fact 4: The earth gets 174 Petawatts of incoming solar radiation in the upper atmosphere. About 30% is reflected back to space, and the rest is absorbed by oceans, clouds and landmasses.
Fact 5: The water cycle is an important result of solar insulation. The earth, oceans and atmosphere absorb solar radiation and their temperature rises. Warm air rises from the oceans, causing convection. When this air rises to high altitudes, clouds are created by condensation of water vapor. These clouds cause rains that bring water back to the earth's surface, which completes the water cycle.
Fact 6: Solar energy also has Another use. By means photosynthesis, solar energe is converted into chemical energy by green plants, which creates the biomass tha makes up fossil fuels
Fact 7: Horticulture a agriculture seek to make the maximum use of solar energy .These include techniques lik the timing of planting cycle and the mixing of plan varieties. Greenhouses are also used to convert light in theat to promote year-roun cultivation of special crops
Fact 8: Solar powered hot water systems utilize solar energy to heat water. In certain areas, 60 to 70% of the water used domestically for temperatures as high as 60 degrees Celsius can be made available by solar heating.
Fact 9: Solar chimneys are passive solar ventilation systems. Shafts connect the interior and exterior of the building. The functioning can be improved by glazing and using thermal mass materials.
Fact 10: Solar energy can also be used for making potable,brackish or saline water.Without using electricity or chemicals, wastewater can be treated. Creating salt from seawater is also one of the oldest uses of solar energy.
Fact 11: Clothes can be dried in the sun using clotheslines, cloth racks etc.
Fact 12: Food can be cooked, dried or pasteurized using solar energy.
Fact 13: Solar power is the most exciting use of solar energy. It is how solar energy is converted into electricity by using either photovoltaic (direct method) or concentrated solar power (indirect). Large beams of sunlight are focused into a small beam using mirrors or lenses in the case of concentrated solar power. The photoelectric effect is used by Photovoltaic to convert solar energy into electric energy.
