Last week, the Austin City Council approved a $2.3 billion purchasing agreement with what will become the largest wood-waste-fueled biomass plant in the United States. The city will buy all power produced by the 100 megawatt facility for the next 20 years
Once completed—which should be sometime in 2012—the Sacul, Texas plant will be the largest of it’s kind in the country. The facility will generate power from burning wood waste from logging and mill operations, urban waste from tree clearing and trimming, and from shipping pallets.
All sources of fuel are required to meet Texas Renewable Energy Credit Standards and Texas Forestry Management Practices.
Businesses and some environmental groups have nonetheless voiced concern over the cost of the project and its environmental impact.

Exelon, the largest operator of nuclear power plants in the United States has filed a license application with the US Nuclear Regulatory Commission (US-NRC) to build two new nuclear power plants near Victoria, Texas. When operating, the plants will produce zero units of carbon dioxide, nitrogen oxides, mercury, sulfur oxides, and fly ash.
Exelon has chosen the Economic Simplified Boiling Water Reactor (ESBWR) marketed by GE-Hitachi Nuclear Energy. Each of the reactors will produce approximately 1,500 MW of electric power.
One of the key design features of the ESBWR is a large degree of passive safety provided by large water reservoirs, natural coolant circulation and safety systems that operate without any electrical power. (Link to animation of ESBWR safety system operation)
The EPA dealt Texas a hard blow on Thursday. It turned down the state’s request for a reduction to our Renewable Fuels Standard (RFS). A decision that some environmentalists are sticking in the plus column for biofuels. I can’t say I agree.
It’s not that I’m not on the biofuel bandwagon. I am. Just don’t run the bandwagon on ethanol.
Following an analysis that included reviewing 15,000 public comments, U.S. Environmental Protection Agency (EPA) Administrator Stephen L. Johnson today announced his decision to deny a request submitted by the State of Texas to reduce the nationwide Renewable Fuels Standard (RFS). As a result, the required total volume of renewable fuels, such as ethanol and biodiesel, mandated by law to be blended into the fuel supply will remain at 9 billion gallons in 2008 and 11.1 billion gallons in 2009.

Several weeks ago, Venezuela President Hugo Chávez provided free energy-saving light bulbs to some low-income residents of Houston, Texas. This magnanimous act probably gained him a few American fans. In late March of this year, he also announced his plan to fund “an energy revolution” in Venezuela.
The revolution has an emphasis on using Venezuelan produced products like PVC pipes to construct homes. Another major component of the revolution includes an initiative to make Venezuela more self-sufficient in food production, thus quelling the need to import food. Projects to provide additional electrical power through alternative energies like wind and solar technologies are also commencing.
The most notable and measurable success to date for the so-called energy revolution, however, has been Venezuela’s effort to change out standard light bulbs across the country for CFLS (energy-saving compact flourescent light bulbs) exactly like those Chávez donated to Texans. So far, 72.3 million light bulbs have been changed. But the story is perhaps not as simple as it would seem (as is almost any story about Chávez and his schemes).
By now, we all know it’s cheaper — and more environmentally friendly — to walk or bike to places than to drive a car or SUV. But is the low-cost, low-impact way always feasible in the motor-happy, open-freeway-obsessed U.S. of A.? That’s what we’ll be exploring this week at EcoLocalizer in a feature we’re calling “Walk This Way.”
The question of whether to walk, bike or take public transportation is a no-brainer if you live in a city like New York, where driving can often be more of a pain than a pleasure. But what about the rest of the country? Not every community is large enough or dense enough to offer the auto alternatives the Big Apple does. And what about people who live in rural areas where everything is a half-hour’s drive away or more? Can we refashion our country’s way of getting around to be more European? Or are those of us in unwalkable communities doomed to either move elsewhere or live like so many billions do in the rest of the world, consigned to life in a radius of space measured in only a few miles?

Texas has reportedly applied for a waiver of the current ethanol standards. The Energy Policy Act provides an option for a waiver only if the environment or economy would be severely harmed because of the Renewable Fuel Standards.
We’ve all heard of the Information Superhighway; Now it’s time to welcome the Wind Power Superhighway.
In what is purported to be the largest investment in clean, renewable energy in US history, Texas has been given preliminary approval for a $4.9 billion plan to build transmission lines to carry wind power from West Texas to urban areas such as Dallas.
Texas is already the national leader in wind power, but the new transmission lines will make sure wind energy is used to its fullest potential, since most of Texas’ wind power is produced in windy West Texas. The new plan won’t directly create new turbines, but it will add enough transmission lines to move 18,000 megawatts. That’s enough energy to power 4 million homes.
The superhighway won’t just help facilitate the spread of wind power; supporters think it will also create jobs, lower energy costs, and reduce pollution.
Converting the U.S.’s ample and renewable volumes of cow manure into biogas could provide as much as 3 percent of the nation’s electricity needs, say two researchers at the University of Texas at Austin.
In a new study published in the online journal Environmental Research Letters, Amanda Cuéllar and Michael Webber conclude that harnessing the full potential of cow poop power could not only help generate as much — or more — electricity as wind and solar power do today, but could greatly reduce greenhouse gas emissions.

When one of Texas’s richest oil men bets big on wind energy, it gets attention. Yesterday NPR’s Living on Earth broadcast an interview with Mr. Pickens, who shared the salient facts about his planned wind project:
- It will be the largest in the world, he reckons, at 4,000 megawatts
- It will provide enough power for 1,300,000 homes
- It’s a $10 billion dollar project from which he plans a 15%-25% profit
Asked why he is investing in wind now, Pickens replied:
“For a number of years I’ve watched the wind turbines develop — and I feel like it’s time for it. I think that oil has peaked at 85 million barrels in the world. We’ve got to develop other forms of energy — wind, I think solar will be next, and I hope I’m still around to be in the solar deal.” (Pickens is 80 years old.
But what if Congress doesn’t vote to extend the wind Production Tax Credit?
Across the U.S., researchers, startup companies and investors are exploring the potential of creating large amounts of green, renewable fuel from the humblest of sources: algae.
If you think the energy/food potential for hemp is underutilized, wait’ll you get a gander at algae. This little microorganism really packs a punch.
According to The Book of General Ignorance: Everything You Think You Know is Wrong (2006, Harmony Books) (I highly recommend it, by the way — it’s packed with fascinating information and weird insights), algae breathes out more oxygen than all the world’s land-based plants and trees combined. Certain types of algae also deliver a whopping amount of protein and nutrients per farmed acre (20 times more than soy beans, in the case of spirulina).
