Since the fuel costs are increasing a lot so there comes the different forms of energy to avoid pollution and increase the green house gas effect.

The European Commission has adopted a third package of legislative proposals to ensure a real and effective choice of supplier and benefits to every single EU citizen. The Commission's proposals put consumer choice, fairer prices, cleaner energy and security of supply at the centre of its approach.

(Washington, DC) Some of the most influential and competitive organizations in the renewable energy industry have now joined together to create the first trade association for organizations that market renewable energy. The Renewable Energy Marketers Association (REMA) has formed to vigorously promote the economic and national security benefits of domestic renewable energy.

I'm going to make a prediction today: you will never drive a hydrogen fueled car. Although hydrogen does indeed have some benefits in certain applications, it's my task today to separate the reality of useful fuel cells from the hydrogen hype. That may seem like a bold statement to you now, but by the end of this article, you'll understand why.

CONVERTING a greenhouse gas into a clean-burning fuel offers two benefits for the price of one. That's the thinking behind a novel process for converting carbon dioxide into methanol at room temperature, developed by a team at the Institute of Bioengineering and Nanotechnology in Singapore (Angewandte Chemie International Edition, DOI: 10.1002/anie.200806058).

This merits revisiting. With the recent collapse of the Spanish market, the correction of the German market and the expected collapse of the French PV market, FITs prove unsustainable or victim of their own success. Once the market picks up, governments can no longer support their price tab. Moreover, they are based on a false premise: the cost of taking a technology through the learning cycle is prohibitive - it requires too many tens of billions.

The topic is complex. Some underlying questions: * Why promotion of renewables was set-up? * What is the complete economic balance of renewables promotion? (expenses in subsidies, but savings in fuel imports, job creation, exports.... some interesting studies have been done on this - see for instance Macroeconomic study on the impact of Wind Energy in Spain - http://www.aeeolica.es/userfiles/file/aee-publica/091211-executive-summary-2009.pdf) * Is the allocation of subsidies cost done correctly? Electricity consumers often pay extra-cost, but benefits go to other pockets. Should there be a cost re-allocation to make the model sustainable? * Is regulatory framework evolving less rapidly than technology? FITs on PV in 2008 could be significantly reduced compared to FITs in 2007, and so on. How to accomodate regulation to that quick cost reduction? * Had governments defined a cap in global subsidies amount? Not really, this explains why they are all reacting to initial plans. * Development of technology and market drives costs down. Why some few countries should make this investment to the benefit of the entire world? * Have we excessively promoted market growth and neglected technology development? Are we paying too much for building power plants with primitive technology?

@Fernando - I agree that the topic is complex. However, I'd refrain from making claims on employment effects. This is an area where secondary effects are rarely taken into account. While I realise these claims are popular, basically nobody knows.

By Jorge Moreno, Environmental and Building Technologies, Frost & Sullivan With more end users focusing on reducing energy costs, energy-saving water-to-water heat pump (WTWHP) chillers are being deployed to reduce a facility's utility bills. A WTWHP chiller is a water-cooled chiller that is designed to produce hot water at a specified temperature. The use of a WTWHP chiller is very similar to a conventional centrifugal chiller except for the fact that it uses two compressors, slightly different piping configurations, and more advanced controls in order to balance cooling and heating loads. In a conventional chiller, cold water is produced for comfort cooling, and the hot water that is extracted from the refrigeration process goes into a cooling tower and is released into the atmosphere. In a WTWHP chiller, this hot water is captured and relocated to a second heating stage, where the temperature is raised and the water is used as a heating source for a building's heating requirements. The key strength of WTWHP chillers is the high coefficient of performance (COP) that translates into significant energy savings and a shorter payback period. On the other hand, the key weakness is that it can only provide such benefits in a narrow range of applications primarily due to its coincident need for cooling and heating requirements throughout the year to ensure efficiency. A coincident need means that the application demands sizable water heating load along with the typical high cooling requirements in summer, and a sizable chilled water load along with the typical heating requirements during winter. Cooling output is directly dependent on the demand for heating, and vice versa. Consequently, in the absence of sufficient heating requirements, there is only a limited amount of cooling that can be produced. Any excess heating or cooling cannot be stored and hence, it is critical to align the cooling with the expected heating requirements. Coincidentally, in the absence of suf

"Decentralised renewable energy solutions linked to livelihoods is an important step in maximising the benefits of energy access for socio-economic development. Renewables offer the opportunity to translate investments in electricity connections and kilowatt-hours into higher incomes for communities and enterprises, local jobs, greater adaptive capacity and overall well-being.

"In the remote county of Tongyu in northeast China's Jilin Province, 14-year-old Li Ruixue has more memories about sandstorms rather than colorful flowers and clean rivers, due to the howling winds that sweep the area from spring to winter every year. Sand-filled winds from Horqin often leaves local farmers' land barren and the United Nations Educational, Scientific and Cultural Organization (UNESCO) has described the county as being one of the areas of the world most unfit for human living. But the Chinese government's new strategy to find more renewable energy might provide one of the country's poorest counties with the opportunity to improve its way of life. The reason for hope is a wind farm with a combined installed capacity of 1.9 million Kilowatt that will soon be completed in the county."

"A new survey conducted by Applied Materials, Inc. reveals that two-thirds of Americans believe solar technology should play a greater role in meeting the country's energy needs. In addition, three-quarters of Americans feel that increasing renewable energy and decreasing U.S. dependence on foreign oil are the country's top energy priorities. According to the survey, 67 percent of Americans would be willing to pay more for their monthly utility bill if their utility company increased its use of renewable energy and 49 percent of consumers polled would be willing to pay $5 or more each month for an increased amount of renewable energy-a 14 percent increase from the results of Applied Materials' 2009 survey. "Americans are becoming more aware of the need for responsible energy solutions, like solar power, and increasingly want their government to drive policy and investment aimed at finding alternative ways to power our homes and economy," said Dr. Charles Gay, president of Applied Solar, a division of Applied Materials. "With the right energy legislation in place, the U.S. could reap the benefits of one of the biggest economic job engines of this century - the clean energy revolution.""

My Clean Break column today is actually more of a feature looking at compressed-air energy storage (CAES) and how Ontario, geologically, would be an excellent location to give it a try. About 50,000 natural gas and oil wells have been drilled in southwestern Ontario over the past 150 years and most of them are depleted. Turns out that depleted gas fields are one of several types of underground reservoir that can be used to store compressed air. Salt caverns are another option, and we have plenty of those as well. In fact, 60 per cent of Canada's natural gas storage is in the region. Compressing and storing air wouldn't be that different technically. Another benefit is that southwestern Ontario has strong wind resources, so building a 1,000 MW-plus CAES facility on its own or as part of a partnership with area wind developers could prove quite economical. The idea, of course, is that cheap wind power generated overnight when demand is down could be used to compress and store the air. The air could then be released to generate electricity during daytime peaks, making wind a dispatchable resource in Ontario and more of a realistic replacement for coal power as it gets phased out of the province. Surplus overnight nuclear power, when we have it (mostly during the summer), could also be stored this way.
