“Rob Hopkins reminds us that the oil our world depends on is steadily running out. He proposes a unique solution to this problem — the Transition response, where we prepare ourselves for life without oil and sacrifice our luxuries to build systems and communities that are completely independent of fossil fuels. “>
Fossil Fuels vs. Renewable Energy Resources By Eric McLamb, September 6, 2011 ecology.com
“..The sun also provides enough energy that can be stored for use long after the sun sets and even during extended cloudy periods. But making it available is much easier said than done. It would be cost prohibitive to make solar energy mainstream for major world consumption in the near future. The technology is pretty much ready for many business and consumer applications, but it would be way too expensive to replace the current energy infrastructure used for fossil fuel energy. Still, according to the European Photovoltaic Industry Association, solar power could provide energy for more than one billion people by 2020 and 26 percent of global energy needs by 2040…”

Burlington’s switch to renewable energy will reduce greenhouse gas emissions, save $20 million over the next 20 years and keep energy prices stable, according to Ken Nolan, manager of power resources for Burlington Electric…”
Pros & Cons of Wind Energy windustry.org
“In the U.S., the greatest source of human-caused greenhouse gas emissions is the power sector, at about 38%. The largest source of power is coal, which, even though it produces less than 40% of the power, produces over 70% of the power sector’s greenhouse gas emissions. (20% of the greenhouse gas emissions are from natural gas-fired power plants.) Although wind turbines have become familiar in much of the U.S., wind power still (2013) only accounts for about 4% of the power sector.
The potential for wind energy is immense, and experts suggest wind power can easily supply more than 20% of U.S. and world electricity. The advantages and disadvantages of wind energy are detailed here to help you decide what the future of wind should be in the United States.

http://facebook.com/ScienceReason … In 1979, Jimmy Carter, in a visionary move, installed solar panels on the roof of the White House. This symbolic installation was taken down in 1986 during the Reagan presidency. In 1991, Unity College, an environmentally-minded centre of learning in Maine acquired the panels and later installed them on their cafeteria roof.
In “A Road not Taken”, Swiss artists Christina Hemauer and Roman Keller travel back in time and, following the route the solar panels took, interview those involved in the decisions regarding these panels as well as those involved in the oil crisis of the time. They also look closely at the way this initial installation presaged our own era.

How Green Are Those Solar Panels, Really? By Christina Nunez, National Geographic PUBLISHED November 11, 2014 news.nationalgeographic.com
As the industry grows, so does concern over the environmental impact.
“..Fabricating the panels requires caustic chemicals such as sodium hydroxide and hydrofluoric acid, and the process uses water as well as electricity, the production of which emits greenhouse gases. It also creates waste. These problems could undercut solar’s ability to fight climate change and reduce environmental toxics…
Right now, solar panel recycling suffers from a chicken-or-egg problem: There aren’t enough places to recycle old solar panels, and there aren’t enough defunct solar panels to make recycling them economically attractive….
The silicon used to make the vast majority of today’s photovoltaic cells is abundant, but a “silicon-based solar cell requires a lot of energy input in its manufacturing process,” said Northwestern’s You. The source of that energy, which is often coal, he added, determines how large the cell’s carbon footprint is…”

The French government has announced plans to install solar panels on 621 miles of road over the next five years as part of the “Positive Energy” initiative. The goal of the project is to supply electricity to 5 million people, or about 8 percent of the country. The “Wattway” photovoltaic solar panels that will be used in the project were jointly developed by the French road construction company Colas and the National Institute for Solar Energy and were unveiled last October. We look at the major step forward for green energy on the Lip News with Jo Ankier and Elliot Hill.
Solar Road Panels Offer Asphalt Alternative By Sören Harder .spiegel.de
“..The idea is as simple as it is ingenious. Wherever roads are laid, solar panels could go instead. They would generate electricity, which would in turn be fed into the grid. Thus, oil is conserved twice: Electric cars could be charged with the energy produced by the panels, and the panels would replace the use of asphalt, the production of which requires petroleum…

There’s just one catch: Currently the solar road panels cost about three times as much as conventional roads, the Brusaws say. But over time, they add, the technology could begin to actually turn a profit. It sounds almost too good to be true. “
First AMAZING Solar Roadway UNVEILED!
“Published on Oct 11, 2016
The words failure of epic proportion are thrown around a lot these days….. however Solar Roadways grand unveiling may have just raised the bar on what that actually means.
We were promised roads that would generate power, be computer controlled, modular, replaceable, with programmable lights that would function as road markings that would be visible during the day.
What was delivered was a ‘road’ that couldnt be driven
DIDNT GENERATE ANY POWER
had LED lights on that just cycled
LED that were not visible even when the STREET LIGHTS WERE STILL ON, let alone in full daylight!
and of course 75% of them died within a week of instillation.
You too can now watch the brilliance of the REALITY of solar freakin roadways live!
You would have thought such a failure to achieve anything would have dampened their bold claims…. but not at all, they are now claiming the road will recharge your electric car while you are actually driving……sigh…. and they STILL get wall to wall favorable media coverage!
Could Solar Panels Replace Concrete Or Asphalt Roads? Quora , Contributor Jun 5, 2014 @ 11:54 AM forbes.com
“Yes, they could. The basic engineering of Solar Roadways seems robust and fairly well thought through. Could they do so economically? It’s very difficult to see how…
Solar Roadways make them a lot more expensive — 10 to 40 times more expensive depending on assumptions — and in theory create the ability to avoid some costs and make some other costs more viable, but a lot of the additional value seems pretty flimsy. They will be unable to overcome this massive cost increase through generating electricity.
For example, they want to replace painting road markings — which would degrade the light hitting the solar panels — with LED road markings. Well, this just adds a lot of cost and heat, won’t necessarily be particularly visible during the day and will put LEDs and their wiring between the panels and the sunlight too. Ditto magically moving lane markings allowing shifts in traffic patterns will likewise be an expensive technical solution to some paint which needs to be restored every year or two and maybe some overhead signage…
So what’s the problem with snowplows? Well, they have heavy metal blades that scrape across the road. And the road in this case is a bumpy glass surface, because a slick surface would become a sheet of ice in the rain, so it needs to be textured. And the snowplow blade is going to be blasting across these bumps at 30-50 miles per hour scraping them off and shattering them. Oh, and leaving a lot of snow packed into the cracks between the bumps, degrading the effectiveness yet again. Salt, gravel and other substances will likely be required as well, which is fun when you have a bunch of glass panels with cracks between them allowing salty water in among the solar panels, LEDs, wires and heating coils…”

Wyoming proposal would require utilities to use fossil fuels
Mead Gruver, Associated Press Wed, Jan 25 2:36 PM PST yahoo.com
“..The legislators’ push to punish renewable energy use “clearly picks a preferred energy source regardless of cost. This may not only cost ratepayers and consumers in Wyoming, but it could harm our potential to attract new industry,” Godby said.
The bill would penalize utility-scale solar and wind because those producers are less able to respond quickly to fluctuating demand for power. Natural gas power plants can fire up quickly when millions of people turn on their air conditioners during a heat wave.
But the wind does not blow all the time and solar energy installations cannot produce electricity at night, making them less versatile than fossil fuels that can be burned whenever electricity is needed…”
