The Essentials for the Necessary
Transition to a Renewable Energy Economy

Jan 28, 2012 - Fossil fuels are going to disappear, whether we like it or not. Petroleum, natural gas, and coal are becoming scarcer, harder to extract and a greater danger to the global climate.
If we proceed with business-as-usual, energy companies will take advantage of increasing scarcity to dominate the world economy by vacuuming up more money from the 99%. They will be able to ally with military and financial institutions to construct an energy-military-financial complex that could eventually reduce most of the rest of us to a form of debt peonage.
On the other hand, if we could possibly elect a government that does what governments do best – build infrastructure – we can avoid a world of global warming and economic collapse by building enough wind farms, solar panels, and geothermal systems to power our economy and ignite a sustainable, broad-based period of economic growth. Of course, this will require a sea-change in the direction of the political system, along the lines of the Occupy movement, but there is too much at stake to throw up our hands in despair.
The unfolding energy drama presents progressives with several dilemmas. Some are suspicious that oil scarcity can be used as a ruse by the oil companies and speculators to spike prices. Roger Altman recently argued that a larger supply of fossil fuels will lead to less international tension. More generally, progressives sometimes fear that advocating for less oil use will be seen by the public as an attack on the American Dream of a car in every garage and a single family home for every family.
But in addition to problems of scarcity and extraction, fossil fuels are bringing us towards extremely dangerous climate change. We need to have some answers or else the Right will simply keep up with the chant of “Drill baby drill.” It's time to counter with, “Build, build, build!"
Dirty fuels Create an Unsustainable economy
The question of the future of the supply of fossil fuels is not an easy one to answer. Oil producing nations, for instance, are not at all transparent about their supplies. Technologies constantly change, and so do environmental hazards. However, if we look at the current state of fossil fuel industries, it should be clear that we are in trouble.

The road surface would replace traditional asphalt with 20 km (12.4 miles) of “solar roadways” consisting of a dense grid of solar cells coated with a transparent and durable plastic coating providing 11.2 million kWh per year. The designers say this system, combined with the 26 wind turbines integrated underneath the bridge generating 36 million kWh per year, would provide enough electricity to power approximately 15,000 homes. 
Name your main fret. Are you suffocating with fear of greenhouse gases? An acre of bamboo absorbs 33% more carbon dioxide and releases 35% more oxygen than hardwood trees. Forests of bamboo—which can thrive at subtropical sea level and on 12,000 foot mountains—can provide our lungs with an increase of our favorite gas.
Solar power tower systems such as the ISEGS on the other hand focus a large area of sunlight into a single solar receiver on top of a tower to produce steam at high pressure and temperatures of up to 550 ° C (over 1,000° F) to drive a standard turbine and generator. The ISEGS also uses a dry-cooling technology that reduces water consumption by 90 percent and uses 95 percent less water than competing solar thermal technologies. Water is also recirculated during energy before being reused to clean the plant's mirrors.
