A Solar Structure That Cools in the Sun

Keeping buildings cool in the summer is hard enough as it is and we have access to air conditioning technologies. Now, there’s a better way to keep buildings, cars, and whatnot thanks to some research out of Stanford University. Their new approach to cooling entire structures doesn’t require electricity and means that air conditioners won’t be needed and thus a huge decrease in energy consumption can be achieved.

A team of researchers at Stanford has designed an entirely new form of cooling structure that cools even when the sun is shining. Such a structure could vastly improve the daylight cooling of buildings, cars and other structures by reflecting sunlight back into the chilly vacuum of space.

“We’ve taken a very different approach compared to previous efforts in this field,” said Aaswath Raman, a doctoral candidate in Fan’s lab and a co-first-author of the paper. “We combine the thermal emitter and solar reflector into one device, making it both higher performance and much more robust and practically relevant. In particular, we’re very excited because this design makes viable both industrial-scale and off-grid applications.”

2012 Was a Record Breaking Year for US Wind Industry

2012 was a very successful year for the young wind-power energy industry in the United States. Throughout last year over 6,700 were installed around the country with the industry benefiting overall from new investments into the sector.

Let’s hope this is a sign of the future of what;s to come in sustainable energy in the world’s largest economy!

Overall, America ended the year with 45,100 turbines, producing enough electricity to power around 15.2 million households. Wind power added 42% of all new capacity to the grid last year, beating other sources of energy generation.
Rob Gramlich, AWEA’s Interim CEO said: “We had an incredibly productive year in 2012. It really showed what this industry could do and the impact we can have with a continued national commitment to renewable energy. We’re doing what Americans overwhelmingly say they want: making more clean, renewable energy and creating good jobs in US factories.”

Measure Food in Exercise, Not Calories

walking
Yesterday we looked at labelling gas nozzles and today here’s good news about a better way to label food. A series of studies add up to the conclusion that if people were aware of how much walking it would take to burn off food they eat less. Calories can be confusing so by telling people how much time walking it can help people understand how much energy they are consuming.

“People who viewed the menu without nutritional information ordered a meal totaling 1,020 calories, on average, significantly more than the average 826 calories ordered by those who viewed menus that included information about walking-distance,” writes Scientific American. People who saw the menu with walking-distance info also ordered less than people who just saw calorie info.

A Proposal to Label Gas Nozzles

warning
The overwhelming majority of personal cars use planet-killing, people-damaging, production-intesnive engines that consume a product that literally kills us. Most everyone understands this at some level, but it seems they don’t connect their fuel consumption with world hunger, polar bears dying, or even smog. A new organization in Toronto wants to change that.

Our Horizon wants to label gas nozzles at gas stations the same way that cigarette packages are labelled to warn users of potential harm.

“Imagine if we see these labels every time, how long will it be before we demand more from government institutions,” said Shirkey.
Canada led the world when it placed health warnings accompanied by images on cigarette packages, and Shirkey said that he hopes Canada can once again be a pioneer.

“If you’re concerned with helping people but not the environment, it’s like putting a bandage on someone sitting in a boat that has a giant hole in the bottom,” Neville said. “We’re all dependent and addicted to fossil fuels.”

Consumers Care About Social Responsibility

I recall early in the last decade that companies didn’t respond to calls for corporate social responsibility because consumers didn’t care. That seems to have changed, which is a very good thing. Since then, corporations have had to accommodate the growing concerns of people and have even gone so far to create new brands that focus on ethical behaviour. The consumer times are changing!

Treatment of employees is the biggest factor (45%) when people decide how responsible a company is. Environmental impact follows close behind (38%). Transparency, corporate oversight, and impact on society are also important factors.

Companies shouldn’t think that the trend towards socially-responsible purchasing means that they can just claim that their products are “green” and call it a day. According to the survey, 63% of people trust company claims about social responsibility only sometimes–when they do verify information, it’s often by reading product packaging, checking out the news, and doing independent research.
