Solar energy is sufficient in scale to meet all of mankind’s energy needs —- if it can be harnessed and stored in a cost-effective way.
Researcher's solution, already instituted in more than 2,000 households and businesses in Mali, Uganda and Tanzania, involves shared micro-grids with prepaid metering.
The average family spends $2,200 a year on energy bills, nearly half of which goes to heating and cooling
It is becoming more and more common to install solar panels on roofs in order to obtain green electricity, but not all roofs are equally suitable.
Molecular Solar Ltd has achieved a significant breakthrough in the performance of solar photovoltaic cells.
Sanborn Regional School District in Kingston, N.H., has signed the world's first power purchase agreement for ultra-efficient solar hot air, which will reduce heating bills.
Drivers can now continue to keep the air-conditioning system on during the hot sunny days even when they stop the vehicle and switch off the engine. In collaboration with Green Power Industrial Ltd, Hong Kong Polytechnic University's (PolyU) Department of Electrical Engineering has developed an innovative air-conditioning system for vehicles that can turn scorching summer heat into cool air without a single drop of gasoline.
An Illinois research team has succeeded in overcoming one major obstacle to a promising technology that simultaneously reduces atmospheric carbon dioxide and produces fuel.
A team from the University of Wisconsin believes they created a material that could be used to capture energy from respiration.
Siluria is the first and only company to develop an economically advantageous, methane-based alternative for producing fuels and chemicals normally derived from oil.
It is unlikely the United States will meet some specific biofuel mandates under the current Renewable Fuel Standard by 2022 unless innovative technologies are developed or policies change.
Researchers led by MIT professor Daniel Nocera have produced something they’re calling an “artificial leaf”: Like living leaves, the device can turn the energy of sunlight directly into a chemical fuel that can be stored and used later as an energy source.
Using solar thermal energy to power an air conditioning unit can be difficult and expensive. But a team of researchers have added a game-changing advance to the process that could make it much simpler, less costly and more effective.
Electrical energy storage and its management is becoming an urgent issue due to climate change and energy shortage.
Iowa State University's Robert C. Brown keeps a small vial of brown, sweet-smelling liquid on his office table.
More than 10 years after electricity deregulation, the nuclear power industry has decreased greenhouse gas emissions by nearly 40 million metric tons of carbon dioxide and saved $2.5 billion a year as a result of operating more efficiently over the past decade, according to a new study.
Researchers with the DOE's Joint BioEnergy Institute (JBEI) have identified a potential new advanced biofuel that could replace today's standard fuel for diesel engines but would be clean, green, renewable and produced in the United States. Using the tools of synthetic biology, a JBEI research team engineered strains of two microbes, a bacteria and a yeast, to produce a precursor to bisabolane, a member of the terpene class of chemical compounds that are found in plants and used in fragrances and flavorings. Preliminary tests by the team showed that bisabolane's properties make it a promising biosynthetic alternative to Number 2 (D2) diesel fuel.
Here are a few things you can do to keep your home cool and cut that energy bill while we wait for fall and cool weather to arrive.
A sorghum hybrid that does not flower and accumulates as much as three times the amount of stem and leaf matter may help the bioenergy industry, according to a study appearing in the Proceedings of the National Academy of Sciences.
This multipart article analyzes and shares viewpoints on the progress of smart grid initiatives specific to achieving the goals of sustainability in the next decade.
