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.

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.

Read more about this project You may have seen pictures of women in Africa cooking their daily meals on a small cookstove. These cooking implements look remarkably similar to the portable charcoal grills an American family might bring to the beach for an afternoon of grilling hot dogs and hamburgers. Imagine using one of these [...]

Read more about this project CleanStar Mozambique’s founders and investors have this crazy idea that they can make the lives of a few hundred thousand people in Mozambique a lot better, avoid climate-change inducing deforestation, and make money at the same time. RP Siegel shared their six-point plan with us back in September, but in [...]

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.

While the debate on the death of green marketing is far from being over, we see signs that green marketing is not only living but also evolving. Interestingly, these vital signs come from the solar industry, where Sunrun, the largest home solar company in the U.S., is running an advertising campaign that can be characterized as the next generation of green marketing. In other words: welcome to green marketing 3.0.

The “drill, baby, drill” chant may not be heard as often as it was a few years ago, but the sentiment is still very much alive in Washington. However, data shows that the key to unlocking our nation’s energy security isn’t increased domestic production, but rather decreased domestic consumption.

What exactly is a fuel cell? You can think of it as a battery that you add fuel to, in order to keep it going. The fuel, which is always combined with oxygen (or air) to produce electricity, can be as simple as hydrogen. This is the cleanest energy source we know of, since the only byproduct is distilled water.

“The world’s energy system is being pushed to breaking point. Energy-related CO2 emissions are at historic highs, and under current policies, we estimate that energy use and CO2 emissions would increase by a third by 2020, and almost double by 2050. Many clean energy technologies are available but they are not being deployed quickly enough to avert potentially disastrous consequences.”

After quadrupling the size of its Sunnyvale plant last year, Bloom Energy has now broken ground on a 210,000 sq ft. facility in Newark, Delaware that will eventually double its capacity once again. While the cells themselves require time to heat up, that doesn’t seem to be the case for the company’s sales, which seem to be taking off quickly, if their level of fundraising is any indication.

Combined heat & power (CHP) or cogeneration, is really not an energy source itself, but rather more of an energy multiplier, squeezing more usable energy out of each unit of fuel most everywhere it is applied. Without CHP, fuel is used to provide electricity and then additional fuel is used for heat, which in many cases is a missed opportunity. It is most commonly used with a fossil fuel input source today, though it is sometimes combined with biomass or even solar to improve their efficiency.

Naked Energy is a new British start-up company that claims to have invented a hybrid solar technology that can produce both electricity and hot water. The tubular solar collectors produce hot water which is not only useful in itself but it also helps to regulate the temperature of the panel, keeping it from getting too hot, which improve its efficiency.
