The solar thermal method uses energy from theThis tubing is known as solar thermal collectors There is also an indirect method where not water but a non-toxic anti-freeze liquid is used. The sun warms this liquid which in turn transfers this heat to water held in a tank. Passive thermal building design is as simple as designing to maximise the sun’s use. sun directly to generate heat. Solar panels can be used to collect heat from the sun to capture its heat and transfer it for water and space heating in buildings. Commonly such panels are positioned to maximise absorption of heat from the sun throughout the day and contain tubing through which water circulates.
Solar Energy
How it works
*the enrgy from the sun is FREE *The payback period for this investment can be very short depending on how much electricity your household uses. *If your system produce more energy than you use, your utility company can buy it from you, building up a credit on your account! *It will save you money on your electricity bill if you have one at all. *Solar energy does not require any fuel. *It's not affected by the supply and demand of fuel *The savings are immediate and for many years to come. *The use of solar energy indirectly reduces health costsposter yourself
Its advantages
The initial cost is the main disadvantage of installing a solar energy system, largely because of the high cost of the semi-conducting materials used in building one. The cost of solar energy is also high compared to non-renewable utility-supplied electricity. As energy shortages are becoming more common, *Solar energy is becoming more price-competitive. *Solar panels require quite a large area for installation to achieve a good level of efficiency. *The efficiency of the system also relies on the location of the sun. *The production of solar energy is influenced by the presence of clouds or pollution in the air. *Similarly, no solar energy will be produced during nighttime although a battery backup system and/or net metering will solve this problem. *As far as solar powered cars go - their slower speed might not appeal to everyone caught up in today's rat race.
The disadvantages
Solar energy is completly renewable, because it not like we will run out of sun will we. I think solar energy is a great earth friendly power sause and i think we should use it because its FREE, it dosen't polute the air and you can make the most of the sun.
Is it renewable and why i think we shold use it?
