Potential market for residential fuel cells and combined heat and power systems.

Fuel cells are already powering hundreds of installations world-wide from cell phone towers to large scale facilities. In the United States fuel cells are providing low-carbon electricity to businesses such as Whole Foods grocery stores in New England and Sierra Nevada's brewery in California. Fuel cell power systems can also be used to generate power in your home.

Solar Industry Growing; Obstacles Remain Poll Says

According to a new poll from Droege & Comp. and Gibbs & Soell, U.S. Solar businesses are poised for strong growth in 2010 and significant growth in 2011. However, respondents indicate that obstacles still remain. Favorable legislation, customer knowledge and heightened marketing will be keys to the expansion of their business. Participants included nearly 100 professionals representing key areas of the solar business value chain. Results from the 2009 Solar Industry Monitor were unveiled at the 2009 Solar Power International Show in Anaheim, Calif.

Sustainably Producing Algae Biofuels for a Clean Energy Future

Algae biofuels promise greater productivity, and can be grown on nonarable land, and with mostly non-potable water. However, as with any new technology—especially in the biofuels space— many questions about its technical potential and sustainability remain.

The Italian PV market to grow to 15 GigaWatt

Interview with Federico Brucciani, independent solar PV expert and author of the report "The Italian PV market". Brucciani is very optimistic about market growth in his country. He says that grid-parity will be reached in all market segments within the next 6 to 8 years. He adds that the market is becoming more sustainable than in Spain and that a new and appealing FiT program can be expected as a follow up to the current program, which has met with so much success.

The Promise of Solar Power Has Roots Deep in the Space Program

With Presidential direction and Congressional support, NASA's wellspring of talent could help foster the creation of solar power satellites - spacecraft that circle the Earth and beam the energy they generate down to the ground for distribution as electricity.

Third-Gen Thin-Film Solar Technologies: Forecasting the Future of Dye Sensitized and Organic PV

Third-generation thin-film solar devices are beginning to emerge in the marketplace after approximately 20 years of research and development, due to the insight of leading material developers such as Konarka and Plextronics in the organic photovoltaics (OPV) domain, and Dyesol, EPFL, G24i, Mitsubishi and Peccell on the dye-sensitized cells (DSC) front. Both DSC and OPV technologies lag far behind on the efficiency curve when compared to conventional solar (i.e., >20 percent efficiency), so they will likely succeed in markets where their low cost, substrate flexibility, and ability to perform in dim or variable lighting conditions provide them with a significant competitive advantage.

A Review of "Six Degrees Could Change the World"

Six Degrees Could Change the World is the latest in a steady stream of documentaries to focus on concerns about the environment and global warming since Al Gore's An Inconvenient Truth won the Academy Award for Best Documentary. Six Degrees , though, takes these concepts in a fresh, new direction and in now way, shape or form attempts to imitate Gore's film.

Emerging Trends in Commercial Biofuels Production

The challenges from agricultural requirements to produce food and energy can only be met if we use all options available for increasing productivity and safeguarding harvests. Innovative crop protection products and plant biotechnology provide solutions to reduce the energy consumption in agriculture while conserving natural resources and contributing to mitigate the effect of climate change.

Fuel Cells Enlist in Armed Forces

Fuel cells have the potential to dramatically change how the military carries out its missions, and how soldiers operate in the field. With the largest, most technologically advanced military in the world, the U.S. armed services use an immense amount of fuel and electricity, and any use of alternative energy would have positive effects on reducing greenhouse gas emissions. However, fuel cells are of particular interest to the military not for their environmental savings, but because of unique technical features that can aid soldiers in the field.

How Much Alternative Fuel do we Really Want or Use?

Not all the alternative generation of energy is really taken into account because numerous small-scale projects are inevitably overlooked. The Energy Information Administration (EIA) does make available figures on the economy, crude oil prices, and alternative resources to the best of their data collecting ability. This information is almost constantly revised as more data is available but the changes and revisions are not especially dramatic. The change in energy consumption and sources of energy is an evolutionary process and not a revolutionary process.

Installing Solar Systems in California

As a recognized solar industry pioneer, Gary is 2008 and 2009 President of CALSEIA - the California Solar Energy Association - and a board member of Architects/Designers/Planners for Social Responsibility and Build It Green - using his three decades of knowledge to grow the solar industry for all companies.

Maintaining a Sustainable Energy Mix

This article deals with the present energy mix and tries to discover how the future energy mix should look in order to be sustainable and significantly reduce environmental impact, for example reduced CO2 emissions. It should be less dependent on the fossil fuels, have increased reliability, have fuel cost with reduced price fluctuations and be able to successfully meet the future demand for energy that just gets larger and larger as world energy requirements increase with the new lifestyle choices.

Offshore Wind

The US has installed over 25 gigawatts of wind, and thanks to hodge-podge of policy incentives, research and development, and private investment wind has become the poster-child of renewable energy and at the utility-scale has achieved grid-parity with conventional fossil-fuel energy. However not a single kilowatt of offshore wind has been developed, despite it being a stronger and more consistent energy source than its counterpart on land, closer to large populations where the energy is needed, and already proven commercial technology.
