Solar Energy: Current Situation and Future Possibilities

From the ancient time humans depend on solar energy, heat and radiant light from Sun. Today’s world is facing great problem with energy resources which can be tightened by the use of solar energy instead of depending on the natural energy resources. Most used solar technologies are solar architecture, solar thermal electricity, solar photovoltaics and solar heating. Depending on the way of capture, convert and distribution of energy solar technologies are either passive solar or active solar.

In active solar techniques, photovoltaic panels and solar thermal collectors are used to collect the energy from sunlight, convert them and distribute them as solar energy. On passive solar techniques, it’s necessary to include a building oriented to the Sun, materials with favorable thermal mass or light dispersing properties and of course design a space to circulate air.

Per year Earth’s atmosphere, oceans and land masses absorbs around 3,850,000 exajoules solar energy. From 2002’s statistics it was more energy in one hour then the world used in one 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.

Across all over world solar energy can be gathered by various processes. According to International Energy Agency, harnessed of solar energy will be long term beneficial for the survival of earth. It 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.

The cost of absorption will be nothing in consideration of benefits. If we wisely spent solar technologies cost it will be very easy to construct one. Solar energy will reduce our dependency on earth’s energy resources and we can give our future generation the chance of live in a great environment.

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.
