Ausra's zero-carbon power plants generate electricity at current market prices for fossil-fired power without the emissions caused by burning fuels. Low-cost thermal energy storage systems now under development by Ausra will allow solar electric power to be generated on demand, day and night.

The Commission of the Economic Community of West African States (ECOWAS) works towards a voluntary commitment to the Sustainable Energy For All Initiative of the UN Secretary General presented at the Rio+20. In a regional workshop, held from 25 to 27 June 2012 in Dakar, Senegal, the Directors of the ECOWAS Ministries of Energy agreed on the main targets and pillars of a regional renewable energy and energy efficiency policy of ECOWAS. The policies aim at the following objectives: Around 30% of the electricity consumption in the ECOWAS region will be saved through demand and supply side efficiency improvements by 2030. The share of renewable energy (incl. large hydro) of the total installed electric generation capacity of ECOWAS will increase to 35% in 2020 and 48% to 2030. The share of new renewable energy such as wind, solar, small scale hydro and bioelectricity (excl. large hydro) will increase to around 10% in 2020 and 19% in 2030. These targets translate to an additional 2.425 MW renewable electricity capacity by 2020 and 7.606 MW by 2030. To provide universal access to energy services it is envisaged that around 75% of the rural population will be served through grid extension and around 25% by renewable energy powered by mini-grids and stand-alone systems in 2030. By 2020 the whole ECOWAS population will have access to improved cooking facilities either through improved stoves or fuel switching to other modern forms of energy such as LPG. The share of ethanol/biodiesel in transport fuels will increase to 5% in 2020 and 10% in 2030. By 2030 around 50% of all health centers, 25% of all hotels and agro-food industries with hot water requirements will be equipped with solar thermal systems.

Até agora, a maior iniciativa do governo federal, pensando na diversificação da matriz energética nacional e na segurança do abastecimento, foi o Programa de Incentivo às Fontes Alternativas de Energia Elétrica (Proinfa). Iniciado em 2002, com conclusão prevista para dezembro deste ano, o Proinfa previa a contratação de 3.300 MW, a partir de três fontes renováveis: eólica, Pequenas Centrais Hidrelétricas (PCHs) e biomassa

Um dos maiores potenciais de energia eólica do Brasil, o Ceará foi mais uma vez escolhido para ser gerador da fonte renovável. O Estado deu, nesta sexta-feira (05), mais um passo na caminhada para se tornar autosuficiente na geração de energia, até o ano 2010, e passar até a vender parte do que for produzido. O município de Paracuru, a 90 quilômetros de Fortaleza, inaugurou nesta sexta um novo parque eólico, que está funcionando com 12 aerogeradores.
European Parliament Calls for Renewable Heat Obligations - 0 views

Yesterday, the European Parliament approved by overwhelming majority the "Thomsen Report" on the Roadmap for Renewable Energies in Europe. Crucial for the future of solar thermal: the call for the adoption in all Member States of renewable heat obligations, at least in new buildings and those undergoing major renovation.

A molten salt system1 is a means to store thermal energy, thus mitigating the problem of an intermittent source for generating electricity at night or during cloudy weather. It is one of Tom Konrad2’s top ten favorites for an alternative energy future because it’s cheaper to store heat than it is to store electricity and concentrating solar power can produce a ton of heat without pollution or fuel.

Energy-Saving House with W Generation System Opened to Public :: PNN Planet2025 News Ne... - 0 views

Osaka Gas Co. of Japan announced that an energy-saving house in Saito Asagi, Ibaraki City, Osaka Prefecture, equipped with a "double-generation system," which is made up of a co-generation system using a household-type polymer electrolyte fuel cell and a solar photovoltaic system, would be open to the public. The house will remain open until the end of May 2008.The fuel cell is rated at one kilowatt and simultaneously generates power and heat, with the heat being effectively utilized for heating water. The combination of the 4-kilowatt photovoltaic system and this fuel cell enables the average household to reduce primary energy consumption by about 55 percent and carbon dioxide emissions by about 70 percent over conventional systems.Moreover, although blinds are typically set inside of windows, the blinds in this house are set outside of windows in order to cut sunlight in the summer, while absorbing thermal energy from sunlight in the winter and transmitting it to the specially designed walls; thus, energy requirements for heating and cooling are reduced. With the latest gas facilities and home-security systems, visitors can enjoy experiencing the exceptional functionality this concept house offers.
