Solid-state lighting technologies, which include both LED and organic light emitting diode technologies, have the potential to save Americans $26 billion a year in energy costs by 2030.

The sea has long been a source of Norway's riches, whether from cod, farmed salmon or oil. Now one researcher from the Norwegian University of Science and Technology (NTNU) researcher hopes to add seaweed to this list as he refines a way to produce "biocrude" from common kelp.

The device consists of the mesh solar panel, which acts as the first electrode, beneath that is a thin sheet of porous carbon that is the second electrode and a lithium plate that is the third electrode. Between the electrodes are sandwiched layers of electrolyte for carrying electrons back and forth.

The new energy efficiency standard’s positive environmental impact includes 3.63 quadrillion BTU’s of energy saved during the above mentioned period, that translates in avoiding 265 million metric tons of CO2 emissions equivalent to the annual emissions of about 52 million automobiles.

Indian wind energy companies are looking to invest in offshore wind energy projects as the government plans to significantly increase the annual capacity added in the wind energy sector as a whole.

Nine out of 10 Australians have considered, or would consider, switching to solar energy as a way to cut their power bills, a new survey has found.

Washington State University researchers have developed a new catalyst that could lead to making biofuels cheaply and more efficiently.

The United Nations Environment Programme (UNEP) has launched a new initiative to accelerate the transition to more efficient appliances and equipment to reduce global energy demand, mitigate climate change and improve access to energy.

Texas Tech University researchers will receive $1.4 million from the U.S. Department of Energy to develop a new radar prototype that will provide better measurements of the complex flow conditions in wind plants.

All eyes are on New York City this week, as world leaders come together for the U.N. Climate Summit – an event that aspires to shape the national and global energy future.

Components of the battery are made from alfalfa and pine resin, and can be recycled using a low energy process and non-hazardous chemicals like water and ethanol, unlike regular lithium batteries that require high energy processes using hazardous chemicals to recover any reusable components.

A new project helps give kids a safe place to play soccer in a Rio de Janeiro favela by using kinetic-energy harvesting tiles to produce electricity for keeping the lights on.

The Environment Ministry will begin a model project in which surplus electricity generated from renewable energy sources, such as wind and solar power, will be utilized to produce hydrogen for fuel-cell vehicles.

The typical restaurant uses five to seven times more energy per square foot than office buildings or retail stores. And if you are running a high-volume quick service establishment, you may be using up to 10 times more. All these energy costs can eat into your profits.

A review of the Energy Efficiency Improvement Scheme has found that the program saves participating households about $1600 each, Minister for the Environment, Simon Corbell, announced yesterday.

Businesses in the US are expected to save nearly $45 billion (£27.6bn) on their energy bills, thanks to funding announced for energy efficiency and renewable projects.

A desalination technology powered by solar panels could provide enough clean, palatable drinking water to meet the needs of India's water-deficient villages, MIT scientists say.

The UK’s Defence Infrastructure Organisation (DIO) has seen savings of more than £2 million so far by investing in energy efficient lighting.
