The thing about fossil fuels is that they enable utilities, planners and policy-makers to, in effect, be dumb.  Because fossil fuel is essentially stored solar energy, the fuel can simply be pulled out of the ground, transported to a large power plant and burned.  No attention needs to be paid to wind speeds, cloud cover or tides.  Of course, we know that the entire supply chain of conventional energy--from extraction, to processing, to transportation and on to burning the fossil fuel--lead to social, political and environmental degradation, the costs of which are getting higher and higher. 

Moving to renewable energy sources helps mitigate those costs, yet it also forces societies to be smart about energy.  To put it simply, that’s because renewable energy sources are variable, and different regions can posses vastly different renewable resources.  This variability can be a problem for utilities, because they need to constantly supply enough power to meet demand.  According to a recent study by the Rocky Mountain Insitute (RMI), “In the past, utilities believed that they had to compensate for this variability by installing more traditional, fossil-fueled power plants. The more wind or solar power on the grid, the thinking went, the greater the need for backup generating facilities to be there when the wind or sun wasn’t.”

Two Models for Financing the Energy Revolution

We Don’t Need Better Panels but Rather Better Politicians and Bankers
One of the key aspects of Gore’s challenge to produce 100% of America’s energy from renewable sources within a decade is his belief that we already have the requisite technology to do so.  And in fact, most experts will tell you that while meeting his challenge will require a lot of innovation, (we need to develop better grid control and energy storage systems, for instance) the main challenge is not technological but rather political and financial.  In other words, we’ve got the engineers and designers, but we lack the right kind of politicians and bankers.

The political challenge is best exemplified by the fact that the Congress left for its summer recess without having extended crucial tax credits for wind, solar and energy efficiency.  As Thomas Friedman pointed out, “both the wind and solar industries depend on these credits—which expire in December—to scale their businesses and become competitive with coal, oil and natural gas.” As a result of political infighting, dozens of renewable energy projects slated to begin next year have been put on hold.

My Challenge to America: Don’t Ignore Gore’s Speech

Last Thursday Al Gore gave a speech, the full text of which can be read here, that challenged America to “to commit to producing 100 percent of our electricity from renewable energy and truly clean carbon-free sources within 10 years.” It was a speech that should have inspired and excited Americans of all walks of life at least as much as, if not more than, President Kennedy’s famous speech calling on America to put a man on the moon within a decade. Instead, Mr. Gore’s idea has been met with a chorus of criticism, with the naysayers claiming that it would be too costly, too impractical, and too risky to attempt to meet such a goal.

Apollo and Gore’s “Moon Shot"--A Flawed Comparison
The comparisons between America’s mission to the moon and Gore’s “moon shot” proposal, while useful, are flawed.  Both represent great challenges, yet it must be remembered that in 1961 we did not possess the technology to get to the moon; we do, however, have the technology to achieve 100% renewable energy.  But perhaps more importantly, although the Apollo program was great for national pride and beating the Soviet Union, it was by no means essential to our nation.  Switching to renewable energy, on the other hand, can not only dramatically reduce our greenhouse gas emissions, it can also help us regain our stature in the world, create jobs, rein in unpredictable energy costs, lower health care costs, get us off foreign oil (provided we also electrify our transportation system) and force American companies to innovate in ways that will be good for them and good for America.

Al Gore Gives Electrifying Speech, Calls for 100% Renewable Electricity Within 10 Years

Gore Gives an Electrifying Speech
Yesterday Al Gore gave an electrifying speech (the full text of which can be read here) that challenged America “to commit to producing 100 percent of our electricity from renewable energy and truly clean carbon-free sources within 10 years.” That’s right: no “reduce carbon emissions by 80% by 2050” or “generate 10% of electricity from renewables by 2020.” Rather, Gore issued a challenge that both captures the enormity of the challenges we face and forces us--all Americans--to devote our passion, creativity and genius toward creating a healthy, clean, and just America.  Of course, meeting the challenge will require not only that the government provide strong incentives for renewable energy, it will also entail getting all sectors of the economy to radically change how they think about, procure and use energy.  And while we already have all the technology we need to produce 100% of our electricity from renewable energy, we lack the transmission lines, control systems and policies that will be needed to make that a reality.  Old jobs will be lost, and hundreds of thousands of new ones will be created.  Where once rooftops contributed to the urban heat island effect and nothing else, solar panels will silently, poetically convert solar energy into electricity; off-shore and on-shore wind turbines will sprout up to harvest the breeze and, in the process, protect land by making it more valuable; in short, the impacts of shifting to 100% renewable electricity in a decade will be far-reaching, all-encompassing and deeply transformative.

Can Americans still think big?
The only question now is, have Americans lost their ability to think big and boldly?  Have 8 years of the Bush Administration made us so complacent that we no longer believe in our ability to meet great challenges?  I for one can say that as a young American, I am extremely excited and inspired by Gore’s challenge.  I want to devote my energy to renewable energy, peace and prosperity.  Just as Obama’s campaign has made so many Americans--young and old--feel hopeful about the country, Gore’s speech makes me feel hopeful and excited about the future of the world.  There are simply too many exciting trends going on for us to sit back and feel there is nothing to be done about climate change, poverty and pollution.

Residential Wind Installations on the Rise, Some Barriers Remain

Written on 07/11 at 12:51 PM by Andy Posner 0 comments

Filed under: environment Renewable Energy News

I recently discussed the fact that renewable energy projects are becoming increasingly large and centralized, a trend that has led some to fear that the “residential revolution” of small-scale wind and solar in every home would never come to pass.  But now, thanks to “reductions in their size and cost, along with improvements in efficiency,” sales of small wind turbines “have been growing steadily since 1990.” 7,000 small turbines (classified as producing no more than 100 kilowatts) were sold last year, a number that is expected to reach 10,000 this year. These turbines are typically rated at between 2 and 10 kilowatts, are from 33 to 100 feet in hight, and range in cost from $12,000 to $55,000.  (For comparison, large wind turbines are rated at up to 3 megawatts, or 3,000 kilowatts, and stand up to 300 feet tall).

Several Factors Behind the Trend
Several factors are driving the increase in sales.  Concern about climate change and energy costs are certainly important, especially considering that “a 10-kilowatt turbine in an area with an average wind speed of 12 miles per hour can lead to a reduction in carbon dioxide emissions equivalent to removing 1.3 cars from the road.” But perhaps the most compelling reason to “go wind” has to do with the economics. 23 states in the U.S. offer net metering, which means that if your wind turbine generates more power than you use, then your meter will actually spin backward as you sell that power back into the grid.  Additionally, Congress is considering a measure that “would offer a 30 percent federal tax credit on turbine purchases” capped at $4,000.  That same federal tax credit is already being offered to residential solar installations.  Lastly, various state incentives can further sweeten the deal.
