Solar Power to Dye For: Flexible Lightweight Inexpensive Dyes Could Harvest Energy from Sun

ScienceDaily (May 10, 2012) — Researchers at the University of Turku believe that flexible, lightweight and inexpensive dyes could be used to harvest the power of the sun rather than our relying on costly and fragile semiconductor solar panel that use crystalline silicon

Writing in the International Journal of Technology, Policy and Management this month, Jongyun Moon and colleagues Aulis Tuominen and Arho Suominen, explain that dye-sensitised solar cells (DSCs) are set to become a ubiquitous source of energy without the complex and expensive clean-room manufacturing processes associated with current solar panels. They point out that the rapid increase in research into novel solar energy conversion technology looks set to revolutionise the industry making electricity generation accessible to all without government or other subsidies.

Solar power is an essential part of the green energy mix, but adoption has been limited in many parts of the world where government subsidies and financial incentives have not been in place. However, as part of a sustainable approach to electricity generation, it offers a clear view of a future in which domestic supply relies less and less on grid power systems or else provides a localised grid for remote places, particularly in sunny climes. Photovoltaic solar cells based on poly-crystalline silicon are the most commonly used devices, having first been used as space satellite technology back in the 1950s and 1960s.

The Military Sheds Its Dependence On OIL – Shouldn’t we be doing the same thing

I know this week and next week, maybe all summer, may look like a chaotic mish mash of subjects but to rejuvenate my sense of purpose I am only blogging about stuff that I find interesting today. I find the military’s attitude towards peak oil to be much more pragmatic then the capitalists they serve.

Energy, politics, and more

 

U.S. military kicks more ass by using less fossil-fuel energy

By David Roberts

This is my contribution to a dialogue on the military and clean energy being hosted by National Journal.

To understand the promise of renewable energy for the U.S. military, it helps to start as far from Washington, D.C., as possible. (This is true for most forms of understanding.) Start far from the politicians, even from the military brass, far from the rooms where big-money decisions are made, far out on the leading edge of the conflict, with a small company of Marines in Afghanistan’s Sangin River Valley

Not long ago, for a three-day mission out of a forward operating base in Afghanistan, each Marine would have humped between 20 and 35 pounds of batteries. One of the reasons Marines are so lethal in such small numbers today is that they are constantly connected by radios and computers. But radios and computers require a constant supply of batteries, brought by convoy over some of the deadliest roads on earth and then piled on the backs of Marines in highly kinetic environments.

In late 2010, India Company, from the 3rd Battalion, 5th Marine Regiment, tried something new. They packed Solar Portable Alternative Communications Energy Systems, or SPACES — flexible solar panels, 64 square inches, that weigh about 2.5 pounds each. One 1st Lieutenant from India 3/5 later boasted that his patrol shed 700 pounds.

Culture Wars – The geezers and the cranks against the future

It is clear that we have to prepare for a future with only clean energy sources in it. Well we used to think everyone agreed with that. But now comes the rich billionaires who have taken over the Republican Party and sucked in all the people who can’t or won’t tolerate change. They want their incandescent lights back.

Is Clean Energy Yet Another Culture War?

May 16, 2012 By

Source: Clean Technica (http://s.tt/1c0hi)

David Roberts of Grist had a great post the other day portraying clean energy as a culture war. I think it’s highly worth a read, so I’m reposting it in full from Grist to make it easy as pie to not pass up (note: there’s also a Part II linked at the bottom of the post that is worth a read):

by David Roberts

Not that long ago, some folks were arguing that clean energy — unlike climate change, which had been irredeemably stained by partisanship (eww!) — would bring people together across ideological lines. Persuaded by the irrefutable wisdom of wonks, we would join hands across the aisle to promote common-sense solutions. It wouldn’t be partisan, it would be … post-partisan.

Some day, I will stop mocking the people who said that. But not today. The error is an important one and it is still made regularly, especially by hyper-educated U.S. elites. They think clean energy is different from climate change, that it won’t get sucked into the same culture war. They are wrong.

On clean energy, the material/financial aspects of the conflict are the easiest to understand. Wind, solar, and the rest threaten the financial dominance and political influence of dirty energy. Last week, the Guardian broke the story of a confidential memo laying out a plan to demonize and discredit clean energy, meant to coordinate the plans/messages of several big right-wing super PACs funded by dirty-energy money.

At the bottom of that same piece, though, is one of the best expressions I’ve ever seen of the cultural and psychological aspects of the conflict

I am fresh out of thoughts on this subject. It all boils down to a decision that ever American has to make. Am I going to take power from the grid or not? If I am when and how? My answer is I would prefer to not get my power from the grid and if I must then as little as possible.

Summer Energy Tips

Summer and the high temperatures it brings can cause increased electrical loads. Keep cool this summer and save energy costs by following these simple tips around the house.

Summer cooling tips

  • Turn off unnecessary lights. Much of the energy from a light bulb is heat.
  • Shut doors to unused rooms.
  • Make sure furniture or drapes do not block your registers for supply and return air.
  • Wear thin, loosely fitting clothes and you may not have to keep room temperatures as cool.
  • Keep the sun out of your house. Close blinds, shades or curtains during the hottest part of the day.
  • On mild days, open windows for natural ventilation and turn the air conditioning off.
  • Use portable or ceiling fans. Even mild air movement of 1-mph can make you feel 3-4° cooler.
  • Apply sun-control or other reflective films on south-facing windows.

Keep Cool with Summer Home Energy Tips

Green Your Home, Slash Your Bills

The prospect of dizzying energy bills, maxed-out power grids, and killer heat waves poses a dilemma for the eco-minded. Crank up the AC, and you’ll burn through countless kilowatts — not to mention your budget. Listen to your green conscience, and you’ll pay with sweat.

But when you maximize the efficiency of your home’s cooling system and adopt smart, low-cost strategies, you can save money and still beat the heat. In fact, by eliminating wasteful habits and power guzzlers, you could cool your home with up to 50 percent less energy and save more than $400 on annual utilities. With 100 million tons of heat-trapping CO2 emitted every year as a result of residential air-conditioning, your new habits will amount to nothing less than a step toward global cooling

Energy Tips For The Summer – Wow this one is real long

Posted on by

What more can I say. This is actually a pretty thoughtful list and like I said long. I will do the first 5 or so and then:

http://www.floridapsc.com/publications/electricgas/20summer.aspx

  1. Close shades, drapes and blinds during the day (all directions).
  2. Wear light weight clothing (short sleeves, shorts, cotton).
  3. Set the air conditioning thermostat at 78 degrees or higher. Raise it a few degrees higher when away in the day. A lower air conditioning temperature makes your costs much higher. Setting your air conditioner at 70 degrees instead of 78 can almost double your operating cost!
  4. Don’t choose a lower air conditioning temperature when you first turn it on. It won’t cool faster –- whenever it’s running it’s cooling as fast as it can. Set low, it cools longer, not faster.
  5. When weather is mild, use fans instead of the air conditioner. Your central air conditioner will use about 100 times more energy than a fan at medium speed.
  6. If you have ceiling fans, run the fans and the air conditioner at the same time but set the air conditioner a few degrees higher, to 80 or 81 degrees. With the breeze from a fan, you should feel as cool as you would at 78 degrees with no fans – but you’ll reduce your costs by about 15%-25%.

But then again they could be 10% of the population and the tips are supplied by Dominion. I mean really a producer advising you how to not consume. Still.

10 Tips to Save Energy and Keep Cool This Summer

  1. Raise your thermostat to 78º. This is the number one way to conserve energy.
  2. When you are away from home for more than eight hours, raise the thermostat setting and you can expect to see a 1% savings for each degree of setback. This will reduce the amount of energy used to cool your home while you’re away. You can learn more about your thermostat online by visiting the U.S. Department of Energy website.
  3. Keep shades closed when the air conditioner is on. Sunny windows account for 40 percent of unwanted heat and can make your air conditioner work two to three times harder.
  4. Check and clean filters. Cleaning and replacing air conditioning filters monthly allows the system to run more efficiently.
  5. Install ceiling fans. Don’t underestimate the importance of ceiling fans. Moving air over the body provides a cooling effect. The use of ceiling fans can mean savings of around 25% on cooling costs and can make the temperature seem 10 degrees cooler.

Guest Blog: Corbett Foundation Mobilizes in India for Earth Day 2012

5/1/12 | Earth Day Network

Guest blog by: Zaara Kidwai

Between April 14 and 23, the Corbett Foundation (TCF) carried out a series of events and activities for Earth Day 2012 in Corbett, Kutch, Bandhavgarh and Kanha, India. We engaged schoolchildren here in a variety of interactive seminars and competitions designed to teach them and their communities about the importance of sustainable living and preserving the environment.

Throughout the week, the Corbett office of TCF organized activities such as environmental film screenings, presentations, health awareness sessions and quiz competitions for 6th-10th graders in 11 schools in and around the Corbett Tiger Reserve.

TCF–Kutch celebrated a one-day mega event on April 22 with children from two schools in Bhuj: Army Public School and Matruchaya Girls School. The event was organized in collaboration with the Gujarat Forest Department, Kutch West Division. A total of 125 students participated in the event, which included a screening of a film about conserving the Great Indian Bustard followed by a drawing and poster-making competition.

TCF-Bandhavgarh organized a nature walk for school children followed by a visit to an interpretation center. They also distributed solar lanterns to the Kulohawah village, located inside the Bandhvagrah Tiger Reserve, and organized an exhibition of traditional crafts.

TCF-Kanha organized an environmental awareness rally and a roadside clean-up in which 70 students and villagers from four villages participated. The rally started in Manjitola village; then, participants marched to the Mukki gate of the Kanha Park. Along the way, students chanted slogans like “Save Earth, Save Life, One Earth, One Chance.”

We hope our efforts will motivate people around us to adopt an environmentally-friendly lifestyle.

Pushing A Mower With No Engine Is Tough – But it is rewarding

Posted on by
Reply

Technically they are called Reel Lawn Mowers. They are not easy to use. They push tough and you have to cut your grass alot because they do not handle high grass at all. For example our mower deck is set at 4 inches, so we cut grass at 6 inches. No way you can do that with a push mower. If you like short grass and you have a small yard, they are perfect. This article takes its own sweet time getting to the point.

Mowing the Grass is Greener When You Don’t Use a Gas-Powered Mower

Lawn Mowers May Account for Five Percent of U.S. Air Pollution, EPA Says

From

Dear EarthTalk: I’ve heard that gas-powered lawn mowers, despite their small engine size, actually pollute as much as cars. If this is true, is there a greener way to cut my grass?
– Jon Haufe, Seattle, WA

Reports about those noxious fumes emitted from gasoline lawn mowers are indeed true. A Swedish study conducted in 2001 concluded, “Air pollution from cutting grass for an hour with a gasoline powered lawn mower is about the same as that from a 100-mile automobile ride.” Meanwhile, the 54 million Americans mowing their lawns each weekend with gas-powered mowers may be contributing as much as five percent of the nation’s air pollution, according to the U.S. Environmental Protection Agency (EPA).

Small Engines Lead to Big Pollution Problems
The problem is that small engines emit disproportionately large amounts of carbon monoxide, volatile organic compounds and nitrogen oxides that contribute to smog. The human health effects of smog-laden air are well known, and include inflammation and damage to lungs, increased risk of asthma attacks, and lowered levels of oxygen in the bloodstream, which can aggravate heart conditions.

New Standards Expected to Reduce Mower Emissions
Fortunately, the EPA is now phasing in new emissions standards for gas mower engines that will result in a 32 percent smog reduction for all models made starting in 2007. And with even more stringent standards slated to go into effect soon in California, environmental leaders are hoping that the old adage for automobile trends (“as goes California, so goes the nation”) will soon apply to lawn mowers too.

10 Things We’ve Learned About the Earth Since Last Earth Day

Sunday is the 42nd celebration of Earth Day, which was started in 1970 by U.S. Senator Gaylord Nelson to help educate people about environmental issues and demonstrate public support for a conservationist agenda. With that in mind, we decided it was the right time to recap the most surprising, awe-inspiring and alarming things that we have learned about the Earth and the environment since last year’s holiday:

1. Undiscovered species are still out there: Countless discoveries over the past year reminded us that, despite centuries of research, the planet still has plenty of surprise species in store. Among the many finds include seven new forest mice species in the Philippines, a “psychedelic” gecko in Vietnam and a new type of dolphin in Australia. A new analysis released last August, billed as the most accurate ever, estimated that a total of 8.7 million different species of life exist on earth.

2. Global warming is already driving up food prices: While many fear that climate change will someday reduce crop yields and cause food prices to rise, a study published last May in Science indicates that this troubling trend has already gotten started. The models used suggest that reduced global yields of wheat and corn are related to global warming. Although the effects are relatively small so far, they may cause severe problems in the future, as climate patterns continue to change and food demand increases.
