Here are a few facts on solar energy that can help you assess the potential of solar energy to meet global requirements. In 2002, this was more energy in one hour than the world used in one year. Fact 7: Horticulture and agriculture seek to make the maximum use of solar energy. The higher the efficiency of the material, the more expensive it will be to manufacture it. When this air rises to high altitudes, clouds are created by condensation of water vapor. Fact 16: The oil crisis of 1970 revealed the delicate nature of fossil fuels as a source of energy for the world. Warm air rises from the oceans, causing convection. As such, research in the alternative, renewable energy technology like that of solar and wind energy gained momentum. Solar thermal systems make heat for space and water heating. Moreover, there are many tax incentives and rebate programs designed to spur the use of solar and save homeowner’s money at the same time. Installation of the solar panels can be really costly; however, they are absolutely worth it. Also, the solar panels might be good to go for a total of 40 to 50 years. Unless you strongly believe in Elon Musk‘s idea of making Mars as another habitable planet, do remember that there really is no ‘Planet B’ in this whole universe. Fact 36: Solar energy is used in many applications, including Electricity, Evaporation, Biomass, Heating water and buildings and even Transport. Fact 12: Food can be cooked, dried or pasteurized using solar energy. 2. Sunlight hits the panel, electrons get moving and produce power. Facts About Solar Energy Today Solar energy is the main source of clean power available for us here on the planet, and we can use this energy to ditch fossil fuels and also to bring the level of our civilization to a new level. The time has finally come to look after some other renewable sources of energy i.e. About 30% is reflected back to space, and the rest is absorbed by oceans, clouds and landmasses. The photoelectric effect is used by Photovoltaic to convert solar energy into electric energy. 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. Fact 16: The oil crisis of 1970 revealed the delicate nature of fossil fuels as a source of energy for the world. About 30% is reflected back to space and the rest is absorbed by oceans, clouds and land masses. Fact 21: Space missions by various countries use solar energy to power their spaceships. Green energy produced by the sun is considered to be the future of alternative energy because it helps combat the greenhouse effect … As of now, only one-tenth of global energy needs is supplied by solar energy, but the potential for the future is mind-boggling. Fact 9: Solar chimneys are passive solar ventilation systems. Fact 10: Solar energy can also be used for making potable, brackish or saline water. In 700 BC, glass lenses were used to make fire by magnifying the sun’s rays. Warm air rises from the oceans causing convection. The only limitation that solar energy possess is that it cannot be used at night and amount of sunlight that is received on earth is depends on location, time of day, time of year, and weather conditions. Fact 28: Solar energy can also be used to power calculators. The battery stores electricity that can be used at a later time, like cloudy days or during the evening.
