Solar Energy Can Build Better Future for next Generation

Radiant light from Sun, heat and solar energy is the main power source for humans from the starting of the civilization. The main problem of this time is the energy resources which can easily be lessened by the use of solar energy instead of depending on the natural energy resources. Solar architecture, solar thermal electricity, solar photovoltaics and solar heating are the main solar technologies available in the present world. Solar technologies can either be passive solar or active solar depending on the way of capture, convert and distribution of energy.

Around 3,850,000 exajoules solar energy are being absorbed by the Earth’s atmosphere, oceans and land masses in every year. Every year the amount of solar energy reaches earth’s atmosphere is so vast that it’s quite double of what we can obtain from earth’s non-renewable resources. From 2002’s statistics it was more energy in one hour then the world used in one year.

Photovoltaic panels and solar thermal collectors are used in active solar techniques to collect the energy from sunlight, convert them and distribute them as solar energy. On the contrary, in passive solar techniques a building is needed to be included which will be oriented to the Sun, materials with favorable thermal mass or light dispersing properties and of course design a space to circulate air.

Solar energy can be gathered across all over world by various processes. For the survival of earth harnessed of solar energy will be long term beneficial, explained by the International Energy Agency. Increased use of solar energy will not only increase the energy security of any country also it will be an independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating climate change, and keep fossil fuel prices lower than otherwise.

If we consider the benefits the cost of absorption will be nothing. With wise and smart thinking we can lessen the cost of solar technology. Our decision will lead our next generation to a great future.

Metal particle generates new hope for hydrogen energy

Led by Associate Professor Greg Metha, Head of Chemistry, the researchers are exploring how the metal nanoparticles act as highly efficient catalysts in using solar radiation to split water into hydrogen and oxygen. “Efficient and direct production of hydrogen from solar radiation provides a renewable energy source that is the pinnacle of clean energy,” said Associate Professor Greg Metha. “We believe this work will contribute significantly to the global effort to convert solar energy into portable chemical energy.”

Inkjet printing could change the face of solar energy industry

Inkjet printers, a low-cost technology that in recent decades has revolutionized home and small office printing, may soon offer similar benefits for the future of solar energy. Engineers at Oregon State University have discovered a way for the first time to create successful “CIGS” solar devices with inkjet printing, in work that reduces raw material waste by 90 percent and will significantly lower the cost of producing solar energy cells with some very promising compounds.
