As we have talked about in previous articles, renewable energy technology such as wind turbines that turn kinetic wind energy into clean electricity or solar technologies that do the same for heat or sunlight is largely intermittent. How can we plan an entire growing global economy that requires power only when the wind blows or when the sun shines?
If you live in North America or pay attention to what is said by U.S. politicians you will have will have heard the term or sound-bite " the war on coal". Does it really mean that certain parties have actually declared a war on coal and if so how do they know if they have won?
Five years ago, solar photovoltaic technology was still very expensive compared to fossil fuel or even wind generation. However every year the price of installed solar PV is falling by at least 5%. Today’s prices for solar panels are so competitive that it is causing a revolution in the global energy industry.
Harnessing sunlight to meet the ever-increasing demand for energy at the global scale has long been pursued by scientists and engineers. In fact, the world needs real alternatives to fossil fuels no more than ever. Before the accident in Japan at Fukushima, many people thought that nuclear power would be the easy ( but expensive ) future source of clean electricity.
Leave it to the land down under to give us another great free training in home solar energy, In this case, a team in Sydney Australia has teamed up with LG solar systems to show a complete home installation of LG solar panels with an inverter to add clean solar electricity to an average size home.
