If the Photovoltaics industry is going to play a significant role in worldwide electricity production in the future it all comes down to one word - scalability, the ability of a technology to expand its production capacity to very large sizes, thereby enabling significant cost decreases.
China may be positioning to change its global image from environmental disasters to an environmental leader, as it was recently recognized as the world leading investor in renewable energy.
While flow batteries and other devices can be used to compensate for wind's intermittent output, it's difficult to match the investor and political enthusiasm for hydrogen.
A "Huerta Solar" is the Spanish term for solar farm and is a grid-connected solar power plant based on several subsystems, each with their own investor.
Looking ahead to 2020, our analysis shows that Scotland could surpass the 40% renewable electricity target, and could easily provide over half of its electricity from renewable sources.
Maybe 2005 - 2006, in retrospect, will have signaled the beginning of the solar boom and be remembered in the history books as the "Dawn of the Solar Age".
With policies both in US and Europe planning for a systematic exploitation of renewable energy on a strategic scale, the stage is all set now for the fuller development of tidal power on a world wide scale.
The results are clear. It is almost $70,000 "better" financially to build a $450,000 ZEH than to build a $400,000 conventionally built home over a five-year period or over any period of time for that matter.
The overall goal of the Chinese government is to have 450 MW of cumulative PV power installed in China by 2010. This is in comparison to the estimated 75 MW which was current in 2005.
In 2005, regulations introduced by the Clean Air Act of 1990 came into full effect with the goal of reducing harmful emissions by 57-billion pounds per year.
What can home appliances do to help ensure the reliability of the electricity grid? A lot—if they employ smart control technology.
Our proposal is to build a completely new US power system, based 100 % on renewable energy sources. These sources are to be solar photovoltaic and wind energy, plus solar thermal energy, with carbon neutral biomass fuels available in reserve, in highly efficient heat engines used to level loads and for backup.
With no fuel-costs, or toxicity, solar PV technology, largely based on our friend "Silicon" offers a truly sustainable means of powering industrial loads. This marks the threshold for our transition from the "Hydro-carbon Man, to the beginning of the "Silicon Man".
