The Price of Solar Plummets, Vindicating Visionaries

Ever since Bell labs developed the first working solar photovoltaic cell in the mid 1950s, people have both lauded the potential--and indeed the poetry--of solar power, while others--the “realists” and “pragmatists"--have derided it as a niche technology whose costs and inherent limitations would always prevent it from overtaking good ol’ fossil fuels and nuclear power as the dominant source of energy for the world.  Unfortunately for the naysayers, the geopolitical, social, environmental and economic impacts of both fossil fuels and nuclear power--which require massive subsidies, cause billions of dollars in health issues, and are tremendously expensive to regulate and clean up after (see my recent article on the spill of coal sludge in the Tennessee Valley)--have begun to far outweigh the supposed affordability and abundance of traditional energy sources.

So while countries like the United States avoided implementing strong subsidies for solar energy and other renewable sources, visionary leaders in Germany and Spain enacted powerful subsidies for renewable energy and compelled utilities to buy that energy at higher rates in order to stimulate the market and create jobs.  Sure, the pragmatists might have argued--and probably continue to argue--that the money being spent on these subsidies, which amounts to roughly 20 cents per month per utility customer in Germany, could be better spent elsewhere.  But in the meantime, Germany has developed into a leader in solar energy, creating tens of thousands of jobs in the process.  Now, according to the New York Times blog, Green Inc., it seems that visionary leadership has begun to bear fruit.  In fact, “On Tuesday, First Solar, a global photovoltaic cell maker based in Tempe, Arizona said it had reached an “industry milestone” by reducing its production costs to the point where making solar cells that produce one watt of power costs $1.”

Coal is Dead: Coal Ash Spill Yet Another Reason to Switch to Renewable Energy

Coal Is An Awful Energy Source
For all the efforts of the coal industry to make it seem like it’s possible for there to be such a thing as “clean coal” (Al Gore’s Alliance for Climate Protection has been running some great ads dispelling that myth), yesterday’s disaster in Tennessee has demonstrated yet another way in which coal is a nasty, dirty, awful source of energy. What happened was the following, as described by the New York Times: a “breach occurred when an earthen dike, the only thing separating millions of cubic yards of ash from the river, gave way, releasing a glossy sea of muck, four to six feet thick, dotted with icebergs of ash across the landscape.” The ash is actually fly ash, “a byproduct of the burning of coal to produce electricity” that “contain[s] significant amounts of carcinogens and retains the heavy metal present in coal in far higher concentrations.” This isn’t the first time such a breach has occurred, though it is probably the worst, having destroyed 15 homes and released 2.6 million cubic yards of toxic heavy metals.  So add toxic sludge to air pollution, climate change, danger to miners, and mountaintop removal to the dangers posed by coal mining and the burning of coal to generate electricity.  Isn’t that enough to convince America to switch to renewable energy?

Considering All the Benefits of Residential Renewable Energy is Critical

I wrote this article for the Huffington Post. It can be found in its original context here.

Ask most people about the benefits of residential renewable energy--geothermal, rooftop solar photovoltaic and solar thermal, and backyard wind turbines, primarily--and the response is usually the same: they are good for the environment, raise property value and lower or eliminate utility bills.  While undoubtedly true, these responses present an incomplete picture of the benefits of distributed renewable energy.  In certain instances, such as last week when a single ice storm left over 1 million homes and businesses in New England without power, a residential energy system can mean the difference between seeking shelter and being able to shelter others.  Other times, particularly during peak demand, renewables stabilize the grid and lower costs for all utility customers.

The Grid Can Fail, and It’s Expensive When It Does
America’s electricity grid is an engineering marvel, but it is also old, outdated, overstrained and susceptible to failure from storms, terrorism, accidents and high energy demand.  And when the grid fails, not only is the loss of power inconvenient, it is also dangerous and costly.  For example, the 2003 blackout that stretched from Canada to New York was estimated to have an economic cost of “between $7 and $10 billion. . .due to food spoilage, lost production and overtime wages” as well as the cost of repairing and upgrading the affected parts of the grid.  While the 2003 grid failure was one of the most extraordinary outages to hit the United States, smaller scale blackouts, particularly from storms and natural disasters, are rather common.

A Financing Mechanism Powerful Enough to Catalyze the Green Economy

I wrote this article for the Huffington Post.  It can be seen in its original context here.

Despite the recent (and undoubtedly temporary) drop in energy prices, the fact remains that because of the economic downturn and an aging housing stock, many families will struggle to heat their homes this winter.  At the same time, the need to create jobs, stimulate the economy, create sound investment opportunities and drastically reduce greenhouse gas emissions has never been greater.  There is no silver bullet for solving all these challenges, but an innovative financing mechanism for renewable energy and energy efficiency could go a long way toward putting the country on the right track.  Here’s how it works.

Homeowners Need Efficiency Upgrades--But Can’t Afford Them
Imagine you are a low-income homeowner in Providence, Rhode Island. Chances are your home is 100 years old: the walls are barely insulated, the windows single-paned, and the boiler a relic of the 1950s.  In the winter your heating bills are such that you can hardly afford to run the heat, often leaving your family shivering.  And even though a $10,000 investment would dramatically lower those heating costs and pay for itself within 5 years, you can hardly pay for the mortgage--let alone $10,000 in efficiency upgrades.

Fossil Fuels Are the Bottled Water of Energy

Written on 08/31 at 08:09 PM by Andy Posner 0 comments

I wrote this article for the Huffington Post.  It can be seen in its original context here.

We already know the numerous reasons why bottled water is bad, including the energy and water it takes to manufacture, ship and discard the product, as well as the fact that tap water must meet more stringent water quality standards.  But here’s the interesting thing: fossil fuels are essentially bottled energy.  And just as the green alternative to bottled water is tap water, the logical alternative to fossil fuels is renewable energy.  Why?  Well, here are just a few reasons (hint: both depend on current flows and are locally available):

1) Like bottled water, fossil fuels are mined from countries around the world, processed, shipped and then, finally, consumed.  This process is wasteful and contributes to environmental degradation, to be sure, but perhaps the greatest downside of a global energy supply chain is that it makes for unstable geopolitics. This may sound like an argument against globalization, but it is nothing of the kind; rather, it is an argument against the globalization of energy. Think about it this way: Thomas Friedman has argued that no two countries that have a McDonalds--that is, two countries that have opened themselves up to global markets--will go to war with one another, because they stand to lose more than they gain.  That theory more or less holds up as long as we are talking about consumer products, fast food chains, and the like, but it falls apart when we start talking about natural resources.  Simply put, energy and water are not Barbie dolls and McDonalds; nations cannot do without them, and therefore the countries rich in fossil fuels hold too much sway on the global stage.
