It’s not diamonds. Nor is it gold. But it might be just as lucrative. European firms this time have their eyes on North African deserts as the location of a giant network of solar thermal plants to provide low-carbon energy for Europe.

In 2001, energy companies across the United States were busy drawing up plans for about 150 new coal-fired power plants. That year, Sierra Club launched its Beyond Coal campaign.
Today, the campaign celebrated its 100th defeat of a proposed coal plant.
“Coal mining is literally blowing the tops of mountains in Appalachia, coal burning is literally heating up our planet, spewing mercury across our landscape, and exposure to coal ash is wreaking havoc on streams and rivers across this country. So in every phase of the lifecycle, coal is filthy business,” Sierra Club campaign director Bruce Nilles said in announcing the milestone.
“We have persuaded the developers, the investors and the decision makers that we can do better than building dirty coal-fired power plants.”
Want to put solar panels on the house? Start saving… solar power is a great investment, but it is an investment… often a hefty one. If you’d like to get started with something a little less ambitious (but more affordable), you’ll find a number of good sources out there for a whole range of solar DIY projects. Voltaic, best known for its solar backpack, has joined more well-known sites such as Gary Reysa’s Build It Solar and Mother Earth News with its own collection of do-it-yourself projects.
So far, the collection is small… but there are already some really cool projects available:
Like millions of Americans, we’re celebrating July 4th, Independence Day.
However, we’re celebrating this national holiday by focusing on the many aspects of our life that, in various ways, have led us to quite a different vision for a sustainable tomorrow – complete with local, renewable energy and lots of delicious meals harvested within ten miles of where we live – if not from our own kitchen garden. Sometimes we even celebrate July 4th with a rainbow.
Here’s how our Independence Day is different — and yours can be too:
• Be energy independent by generating all our power with renewable energy systems.
For a vast portion of the United States, there is enough solar and wind energy to completely meet our needs right where we live. True, adopting renewable energy will require an investment either personally or for your business if you work from home. But with present Federal tax credits and many state incentives, the time couldn’t be better. We completely power our Inn Serendipity Bed & Breakfast and Farm with solar electric and wind turbine systems. In fact, we overproduce renewable energy to the tune of about 4,000 kWhs (kilowatt hours) a year. We share the surplus with our neighbors.

Today we are an oil-based civilization, one that is totally dependent on a resource whose production will soon be falling. Since 1981, the quantity of oil extracted has exceeded new discoveries by an ever-widening margin. In 2008, the world pumped 31 billion barrels of oil but discovered fewer than 9 billion barrels of new oil. World reserves of conventional oil are in a free fall, dropping every year.
As I note in my latest book, Plan B 3.0: Mobilizing to Save Civilization, discoveries of conventional oil total roughly 2 trillion barrels, of which 1 trillion have been extracted so far, with another trillion barrels to go. By themselves, however, these numbers miss a central point. As security analyst Michael Klare notes, the first trillion barrels was easy oil, “oil that’s found on shore or near to shore; oil close to the surface and concentrated in large reservoirs; oil produced in friendly, safe, and welcoming places.” The other half, Klare notes, is tough oil, “oil that’s buried far offshore or deep underground; oil scattered in small, hard-to-find reservoirs; oil that must be obtained from unfriendly, politically dangerous, or hazardous places.”
This prospect of peaking oil production has direct consequences for world food security, as modern agriculture depends heavily on the use of fossil fuels. Most tractors use gasoline or diesel fuel. Irrigation pumps use diesel fuel, natural gas, or coal-fired electricity. Fertilizer production is also energy-intensive. Natural gas is used to synthesize the basic ammonia building block in nitrogen fertilizers. The mining, manufacture, and international transport of phosphates and potash all depend on oil.
You may have gotten your fill of the phrase “energy independence” with last year’s election: both parties and presidential candidates touted the idea repeatedly. It’s a compelling concept… it’s also contentious. For some, energy independence means harvesting solar, wind, and geothermal power; for others, it’s the motivation behind “Drill, baby, drill!” Either way, it’s a challenging goal at the national level.
At the local level, though, energy independence may be realistic… and numerous communities around the United States are exploring available renewable resources, and the technology necessary to harness them. Here’s just a handful of towns creating models for clean energy production… and good old fashioned self-reliance.

By the middle of next year, the nine campuses that make up the nation’s largest community college system plan to be completely energy self-sufficient.
It’s a huge step, and it will begin saving money immediately.
The Los Angeles Community College District (LACCD) started down this path in 2001, the year voters approved the first part of $5.7 billion in bond funding to renovate the campuses.
The LACCD Board of Trustees was thinking about much-needed modernization work and its first new construction in 35 years, but it was also thinking ahead. It passed a sustainable building policy mandating that all new buildings that use 50% or more of bond funding be LEED certified. The board had previously developed a renewable energy plan that aimed for a minimum 10% renewable energy standard.
At the time, the trustees were afraid that anything beyond that would be too costly, says Larry Eisenberg, executive director of Facilities, Planning and Development for the LACCD.
The system’s chancellor and the implementation team saw greater potential, though.
In just seven years the Bonnaroo Music and Arts Festival has emerged as the premier music festival in the United States, if not the world. With the biggest names in music from genres across the musical spectrum taking to thirteen stages and providing festival-goers with four days of good music, danceable beats and pleasing melodies, this year’s Bonnaroo, from June 11-14 in Manchester, Tennessee will be no different from the last seven.
But in addition to the mountains of music and non-musical activities, the festival, which last year was named one of eighteen music festivals worldwide to receive the Greener Festival award, added several new green dimensions to its already impressive greening efforts.
Like the much newer Rothbury Festival up in Michigan, festival organizers at Bonnaroo have been hard at work finding new ways to green the festival scene and engage fans in discussions, seminars and educational programs about important sustainability topics and the pressing environmental issues of today. In addition to incorporating an environmental mission statement into every vendor contract, festival organizers have built upon past successful sustainability efforts and mixed in some new ones to give festival attendees a greener music festival experience.
Below are a few of the pre-festival green highlights, but stay tuned to Green Options for green updates, photos, interviews and reports from the ground at this year’s Bonnaroo Music and Arts Festival. Read the rest of this entry »
Thinking about installing a wind energy system, but not sure if the payback period on your investment meets your financial needs? I began thinking about this question last week when our old friend (and my real old friend) bobbyb sent me an article about a couple who’d installed a wind turbine at their home in Great Britain. He noted that the numbers provided in the article (a £20,000 initial outlay for £500/year energy savings) didn’t make financial sense: “That’s a forty-year payback period!”
He’s right… that kind of cost-benefit analysis doesn’t really work. If you’re going to put up tens of thousands of dollars for a wind system (or a solar energy system), you probably want to see a return on that investment in years, rather than in decades. I got so interested in the topic that I wrote a post about things you should consider before putting your money down on a renewable energy system at SUNfiltered. Wind energy systems have their own requirements, so here are a few of the things you’ll want to take into consideration.
As with any renewable resource, some areas are better than others for home wind energy. Some of the questions you’ll need answers for include
“A new energy economy is going to be part of what creates the millions of new jobs,” President Barack Obama said recently.
That’s because a climate bill, once passed, will act like the starting gun in a business innovation race. To illustrate how capping carbon pollution will stimulate the economy and create jobs, EDF designed this graphic (see below the jump).
