According to a new report published by the Worldwatch Institute, funding for Carbon Capture and Storage (CCS) projects, otherwise known as clean coal, has stalled at the 2010 level of $23.5 billion. This concerns some people because this technology will take a long time to develop. And if we make a half-hearted effort, by the time it is ready to go, it might be too late to make any difference.

If there are still any doubts that biofuels are ready for the big time, last week’s announcement by United Airlines, Boeing, and UOP (a Honeywell company) should put them to rest. The three industry heavyweights have joined with the Chicago Department of Aviation and the Clean Energy Trust to form the Midwest Aviation Sustainable Biofuels … Continued
Last week the state of Hawaii introduced a state-wide ban on plastic bags, becoming the first US state to do so. In spite of significant loopholes, this is a very brave move as plastic bags cause untold environmental problems. Now the city of Los Angeles has banned plastic bags becoming the largest US city with … Continued
The advantages of high brightness light emitting diodes (HBLED) are well known, however widespread adoption has been slow in coming despite a multi billion dollar expected market. This post discusses the rocky road to widespread adoption of HBLEDs.
The Silicon Valley start-up is now on the path to commercializing its solar CPV-thermal co-generation system that provides cooling as well as electricity and heating. Along the way, it’s further improved the economics and efficiency of its technology and realizing the goal of offering customers a firm, consistent source of clean, renewable energy that without any subsidies can compete with any conventional or other alternative energy.
What makes a commercial building “Green” by today’s standards? What are the main things a commercial building can do right now to save on energy costs and reduce their carbon footprint by a great deal? Read more about how commercial led lighting is leading the way to a greener workplace…
An important producer of natural gas and oil, the UAE has become known in the last decade for its growing efforts to fight climate change and advance the use of clean energy. So it’s not that surprising to find out that the UAE is going to represented in the upcoming Rio+20 Summit by a delegation of more than 100 members, aiming to both learn and provide its own lessons to the rest of the world.
On Thursday, the U.S. Department of Commerce (DOC) announced the imposition of antidumping tariffs of more than 31 percent on solar panels from China. The preliminary ruling, if affirmed by the DOC this fall, is expected to have significant implications on the solar industry, creating presumably both winners and losers. Yet, although it might be too early to evaluate the impact of the new ruling, we have a feeling there’s a good chance no one will benefit from this tariff. Is it possible?
Concentrating solar collectors focus sunlight onto a central receiver, amplifying its intensity to achieve very high temperatures that can be converted to steam to drive an otherwise conventional thermal power plant or directly drive a heat engine. Unlike solar PV and solar heating and cooling, CSP adheres to the more traditional centralized utility model, where power is transmitted over long distances.
The term solar thermal has been used to describe two different types of systems. One is where solar panels are used to collect heat, which is used directly, as domestic or process hot water, space heating, or in some cases, air conditioning. This is really the most basic form of solar energy utilization, which is commonly known as solar heating and cooling (SHC).
The truth is, we’ll probably never be paperless due to the many areas where digital simply can’t match the tried and true paper and pen. However, many parts of our society are still consuming far too much paper. Most paper consumption comes from an inability or unwillingness to change our ways, as well as a lack of clear incentives to entice a reduction in the usage of paper.
