Solar Energy: Harnessing the Power of the Sun Soh Zheng Yang, Choy Yu Yong, Tay Wei Sheng and Ng Wei Sing Darren Teacher Mentor: Ms Nada Nurwani Ng School Name: Hwa Chong Institution
Increasing energy demand worldwide is depleting fossil fuels.
The burning of large amount of fossil fuels poses many threats to the environment.
Alternative sources have to be discovered so as to meet the high demand of energy consumption.
Solar energy is a natural and renewable resource, we should hence harness the radiant light energy emitted by the sun and convert it into electrical current.
DISCUSSION AND CONCLUSION
Harnessing solar energy is an alternative form of energy resource and has several advantages:
─ It will be able to produce electricity to satisfy the high demand of electricity using cost effective and eco-friendly ways.
─ It complements the sources of fossil fuels and slows down the
depletion of these non- renewable resources.
─ It is a preferred form of energy resource as is it is a renewable resource, hence, lesser cost will be needed to harness it.
Currently, solar power's contribution to the global energy supply is only a merely of 0.039 percent.
Costly high technology must be used to improve conventional solar panels on Earth, as well as to improve solar energy produced from satellites in space, where lasers from satellites are used to capture electrons.
Researchers should come out with more cost-effective ways to harness the solar energy and at the same time, consumers must conserve the limited energy sources so as to protect our earth and our future!
LITERATURE REVIEW FINDINGS
Electricity can be produced through mainly three key technological advancement:
Thermo chemical solar power
Electricity can be produced when the thermo- chemical technology traps the solar energy and stores it in the form of heat in molecules of chemicals. The heat energy can be converted and into electricity.
Solar Wind Power
The satellite launched to tap solar wind power would use charged copper wire for capturing electrons very far away from the sun and this motion will produce massive amount of energy that windmills cannot do so.
-Solar energy collector
Firstly, the solar panel rests on a rotating pole. This panel keeps on moving with the sun, absorbing solar rays from the Sun. Rotating solar panels follow the Sun’s daytime path. This results in them capturing 20 or 30% more solar energy than stationary ones.
