Coal Consumption Marginalizing China's Renewable Energy Gains - 2point6billion | Sustainable Energy | Scoop.it

China dramatically increased its renewable energy production capacity in 2011, tripling output in solar power alone, but environmentalists warn an unwavering reliance on coal to fulfill 70 percent of its energy needs is offsetting the benefits of this new clean development, according to The Guardian.

Energy Independence: Not the Solution to All Problems

Energy Independence: Not the Solution to All Problems | Sustainable Energy | Scoop.it

The United Kingdom offers a good example. The UK has been roughly oil independent since the North Sea oil fields were developed. Gasoline (petrol in their language) is priced at almost the same level as in the United States when you strip out taxes. Further, UK petrol prices rise and fall with world oil and gasoline prices. So energy independence does not mean cheap and stable gasoline prices.

Energy efficiency in the workplace: which innovations are showing the most ... - Greenwise Business | Sustainable Energy | Scoop.it

The reality is energy efficiency poses more challenges than it addresses right now and, without new inventions, we’re unlikely to be able to tackle them with the urgency required. As Clare Hanmer, Technology Strategy manager at Carbon Trust Innovations, puts it: "There are so many barriers to energy efficiency. It’s not that anyone is missing a trick, it’s just a huge complex problem. You may overcome one barrier, but other barriers get in the way."

Motivating Energy Conservation Behavior without Monetary Incentives

In theory, there are several basic economic and psychological motivators that motivate people to be more sustainable. It is easy assume that providing people with information that using less energy is more cost-effective would motivate a shift toward conservation. However, Fischlein observed that there is often an “energy-efficiency gap,” or a difference between what is economically efficient and what actually gets done. Fischlein stated that “more information alone is not enough,” as increasing awareness has been shown to increase knowledge while motivating little behavioral change.

According to Fischlein, even raising the price of energy might not promote a decrease in consumption because energy exhibits low price elasticity. She also observed “psychological licensing” related to energy use, which effectively means that people lose a sense of moral responsibility for their actions because they have to pay to consume. Motivating altruistic conservation is also difficult because energy use is not visible, so people cannot see the impact of their actions in any direct way.

Interesting perspective. But considering 1500 hours of sunshine per year (on a full-load equivalent basis), and assuming no losses in heat storage, one can run such plant at 17% of nameplate capacity during 24 hours (1500/8760 = 17%).

Feed-in Tariffs in Ukraine ranking among the highest in Europe

Ukraine seeks to reduce its current dependency on gas imports. To address the issue, a number of initiatives are being taken which are aimed at boosting energy efficiency, introducing energy saving technologies and renewable energy resources. The feed-in tariffs effective since April 2009, rank among the highest in Europe, which considering the saturated European market, makes Ukraine especially luring for the foreign investors in the field. As forecasted by the government, in the next 3-4 years Ukraine will be able to attract about 3 billion dollars of private investments for the development of renewable energy production.

Why Energy Efficiency Isn't All It's Cracked Up to Be

Why Energy Efficiency Isn't All It's Cracked Up to Be | Sustainable Energy | Scoop.it

When New Yorker writer David Owen moved his family from Manhattan to a small town in northwestern Connecticut in 1985, it seemed like a green decision. Their tree-shaded house had been built in the 1700s and sat across from a nature preserve. Deer, wild turkeys and even bears could be seen in their yard; woods surrounded their neighborhood. It was a bucolic country existence, something out of a nature poem.

Yet for the global environment, the move was a minidisaster. The Owens' electricity consumption went up more than sevenfold, and the lack of both public transportation and dense housing that's typical of Connecticut (and much of the rest of the U.S.) meant the family had to buy several cars.

Why the Military Hates Fossil Fuels

Why the Military Hates Fossil Fuels | Sustainable Energy | Scoop.it

A strange thing has happened in the politicization of climate change: Oil has become something conservatives must love, while things like energy efficiency and renewable energy have become stand-ins for liberal politics, government intervention, taxes, take your pick. So it is that people are always surprised to learn that one of the biggest proponents of green technology in the United States is that most conservative of organizations, the U.S. military. Reducing energy use, in particular this country’s dependence on fossil fuels, has become a priority amongst all branches of the military pretty much since we got involved in Iraq and Afghanistan, and given that the Department of Defense is the single largest consumer of energy in the country (spending about $4 billion per year on facility energy consumption), it has started with its own house.

Grid blackout threat weighs on renewables take up - EurActiv | Sustainable Energy | Scoop.it

The policy chief of Europe’s electricity industry association has told EurActiv that Europe will have to slow down its integration of renewable energies or risk power cuts and systems instability because of the slow pace of cross-border grid improvements.

 

“Either you go very fast in the transition - which is impossible [because] smart grids are expensive and the storage is not there in the needed scope – or you diminish the speed for integrating renewables into the system,” Susanne Nies of Eurelectric told EurActiv in a phone interview.

A non-sticky gel surrounds the food item when shoved into the biopolymer gel, creating separate pods. The design features no doors or drawers, and the food items are individually cooled at their optimal temperature thanks to the robot. And since it can take any orientation (hung vertically, horizontally, and even on the ceiling), and can be modified in size, you can fit it in any apartment.

More gadget than practical. Not really for families, but great for storing drinks in a bachelor's appartment.
Hans De Keulenaer's comment, February 8, 2012 8:19 PM
Great out-of-the-box thinking. I can not see it really working for a family where a million things are taken out of the fridge for breakfast, and which needs to store fresh items (who wants non-packages foods in contact with gel). But it could work for example in a bachelor's or student's appartment for storing drinks.
Roberto Bogge's comment, February 9, 2012 6:47 AM
I agree with you. It's just a curiosity. A new concept with a lot of possible application, but it's should be re-thought for the daily use on a larger scale. Otherwise it will remain an object of pure design without a real application. Surely also the price will limit the possibility of being traded on large market sectors.
