This week's Graphs of the Week come from the US Dept. of Energy's energy Efficiency and Renewable Energy program, and they address a pretty basic fact of American transportation: The mix of cars vs. light trucks in new vehicle sales, and who's driving them. ("Light trucks" is a term of art meaning pickup trucks, minivans, and SUVs. Add your own rude comment here about how "light" some SUVs are.)

Republicans are not just talking about slowing progress on clean energy, energy efficiency, and climate change, they're doing it…by doing nothing about it. I'm over it. There's a lot of phooey balooey about compromising, reaching across the aisle, Republicans and Democrats working together, a spirit of bipartisanship, a 'new kind of politics'…

The first-ever report exclusively focused on the global human impact of climate change indicates that more than 300 million people are seriously affected by climate change at a total economic cost of $125 billion per year. Earlier today, former UN Secretary-General, Kofi Annan, President of the Global Humanitarian Forum, announced the results of a report on the human impact of climate change. The study, Human Impact Report: Climate Change - The Anatomy of a Silent Crisis, emphasizes the present impacts of a changing climate, pulling the debate away from a focus on "future generations."

Alex at WorldChanging has a look at some recent events in global warming politics - Latest to Sound the Climate Alarm: Doctors, Lawyers, Generals, Bankers and Diplomats.

Two interesting observations: 1. 50% of U.S. power generation (in MWh) comes from coal, while only 20% comes from natural gas. 2. 32% of total U.S. power generation capacity (in MW) is coal-fired, while 42% is gas-fired. When it runs, the natural gas fleet emits just 50% of the CO2 of the coal fleet, which raises a rather interesting question: what would we have to do to make it run harder? And how big a difference would that make in our national CO2 footprint? MW vs. MWh So why, if we have more natural gas generation capacity, do we get more of our power from coal?

China produces 95% of the worlds supply of the rare earth metal, dysprosium, a key metal in magnets used in the drive motors for hybrid electric vehicles - up to 100 grams of dysprosium per hybrid car produced, according to a Wikipedia reference. Dysprosium's magnetic properties also make it an important metal for wind turbines and electric vehicles. Could be vital for MagLev trains, too. Scarcity of the metal is a sustainability and a political issue, according to a recent article in the TimesOnline, Crunch looms for green technology as China tightens grip on rare-earth metals. This does not look good.

President Obama today announced over $467 million from the American Reinvestment and Recovery Act to expand and accelerate the development, deployment, and use of geothermal and solar energy throughout the United States. The funding announced today represents a substantial down payment that will help the solar and geothermal industries overcome technical barriers, demonstrate new technologies, and provide support for clean energy jobs for years to come. Today's announcement supports the Obama Administration's strategy to increase American economic competiveness, while supporting jobs and moving toward a clean energy economy. "We have a choice. We can remain the world's leading importer of oil, or we can become the world's leading exporter of clean energy," said President Obama. "We can hand over the jobs of the future to our competitors, or we can confront what they have already recognized as the great opportunity of our time: the nation that leads the world in creating new sources of clean energy will be the nation that leads the 21st century global economy. That's the nation I want America to be."

As part of a public strategy to offset global warming, the president and Congress are considering possible "cap and trade" laws to limit the United States' carbon dioxide emissions. One question raised in this debate is the amount that such limits would cost United States taxpayers and consumers. Many scientists argue that carbon dioxide emissions are a significant contributor to global warming, and that humanity would benefit if the government did something to stop, or partly offset, global warming.

President Obama's energy secretary, Nobel prize-winner Steven Chu, arrives in Europe this week to discuss global warming. But his recent policy decisions on coal-fired power stations and hydrogen cars have angered many environmentalists US energy secretary Steven Chu will fly to Europe this week to begin talks that will be crucial in the global battle against climate change. The 61-year-old physicist will hold key discussions with energy ministers from the G8 nations in Rome before travelling to London to take part in a debate with Nobel prize winners on global warming.

Some days you have to wonder if everyone who's been sounding the alarm about oil issues for years have been right all along, and the rest of the world, including the US power structure, is just now playing catch-up. At least that's the thought I had when I read BusinessWeek's U.S. Reliance on Oil an 'Urgent Threat': A group of retired senior U.S. military officers has concluded that the country's reliance on fossil fuels undermines its capacity to defend itself. Citing a "serious and urgent threat to national security," the group has urged the Pentagon to take the lead in shifting to a new age in energy.

A new social media site for "experiments in local living" has been launched called "Live Local" which should be of interest to those of you interested in relocalisation and related ideas like the Transition Towns movement. The site aims to be "a place to share stories and ideas about improving your community", with the user generated ideas and stories being dubbed "experiments". live local is a project which we've developed as a joint social venture with Piers Dawson-Damer. The website is a place to share stories about improving our communities. It makes it easy for local residents to document their experiences and adventures meeting neighbours, discovering neighbourhoods, supporting local economies, saving energy, water and much more. At its heart the project encourages people to take more time to connect and engage with their community. I think its clear the alternative; working crazy hours to earn more money to more buy 'stuff' while leaving us little time to get to know our neighbours and spend time with family and friends, has spectacularly failed. Many of us crave a smarter way of living; one that makes us happier. As part of the launch of the site, they have issued the "live local challenge", which encourages people to "live local" for a week.

A GOP senator from the nation's leading coal-producing state contends Democrats will increase energy costs and make the U.S. more dependent on foreign oil if they focus solely on alternative energy. In the party's weekly radio and Internet address Saturday, Sen. John Barrasso, R-Wyo., said Republicans support a more comprehensive energy plan that would increase funding for energy research, develop U.S. oil and gas resources and promote clean coal and nuclear power.

President Barack Obama announced plans on Tuesday for a national fuel-economy and greenhouse-gas standard that would significantly increase mileage requirements for cars and trucks by 2016. Obama called it "an historic agreement to help America break its dependence on oil, reduce harmful pollution and begin the transition to a clean energy economy." The new requirements mark the first time there has been a nationwide standard for emissions of greenhouse gases. They require an average mileage standard of 39 miles per gallon for cars and 30 mpg for trucks by 2016 - a jump from the current average for all vehicles of 25 miles per gallon.

President Barack Obama took aim at climate-warming greenhouse gases on Tuesday and ordered the struggling auto industry to make more fuel-efficient cars under tough new national standards to cut emissions and increase gas mileage. Obama said the standards, announced at a White House ceremony attended by auto industry and union leaders, would reduce U.S. dependence on foreign oil and give five years of cost certainty to an industry battling to survive. "The status quo is no longer acceptable," Obama said in an announcement that will pressure carmakers to transform and modernize the industry to produce more efficient vehicles.

U.S. Commerce Secretary Gary Locke and U.S. Energy Secretary Steven Chu today announced significant progress that will help expedite development of a nationwide "smart" electric power grid. A Smart Grid would replace the current, outdated system and employ real-time, two-way communication technologies to allow users to connect directly with power suppliers. The development of the grid will create jobs and spur the development of innovative products that can be exported. Once implemented, the Smart Grid is expected to save consumers money and reduce America's dependence on foreign oil by improving efficiency and spurring the use of renewable energy sources. Before it can be constructed, however, there needs to be agreement on standards for the devices that will connect the grid. After chairing a meeting of industry leaders at the White House, Locke and Chu announced the first set of standards that are needed for the interoperability and security of the Smart Grid and $10 million in Recovery Act funds provided by the Energy Department to the National Institute of Standards and Technology to support the development of interoperability standards.

The House Energy and Commerce Committee is expected to pass legislation this week that would overhaul U.S. energy and global warming policy, assuming Democrats can stay united in the face of hundreds of GOP amendments. Unveiled Friday, H.R. 2454 (pdf) includes items long sought by environmentalists, including a cap-and-trade program to curb greenhouse gas emissions and a nationwide renewable electricity standard. The 932-page bill, also comes with the support of President Obama, who applauded the "historic agreement" after weeks of intense negotiations among Democrats representing vastly different regions and economic sectors.

A new report released today called Green Cities is one of the first assessments of exactly how 40 of the country's largest cities are trying to limit their carbon footprints and take the steps needed to raise these efforts to the next level. The report was initiated and conducted by Living Cities, a long-standing collaboration of 21 of the world's largest foundations and financial institutions.

Reliable, accessible and affordable energy has been one of the primary pillars of American prosperity since the dawning of the Industrial Age. Unfortunately, many of the energy sources that we have always used have been seriously depleted or produce a dangerous build up of waste products in our common environment. As the people's representatives, Congress wants to help change that pattern by enabling and encouraging entrepreneurs, established corporations and private investors to make the long term investments that will be required to change a pattern of energy use that has been developing for almost 200 years. One attempt at making that possible was the Energy Policy Act of 2005, which established a program where the federal government would back loans for carefully selected projects whose payback profile did not exactly match the demands of the short term thinkers on Wall Street. Unfortunately, that bill put the burden of developing the program onto the Department of Energy, an organization that remains ill equipped for the task. Part of the reason is that the DOE is dominated by other considerations (protection of the nuclear weapons stockpile) and by the established energy industry that has no desire or incentive to make a big change in the current market.

Federal employees and contractors are in a unique position to contribute valuable information and save taxpayers huge sums of money, Angela Canterbury, director of advocacy for Public Citizen's Congress Watch division, told lawmakers today. At a hearing of the House Committee on Oversight and Government Reform, Canterbury testified in support of the Whistleblower Protection Enhancement Act of 2009 (H.R. 1507), to restore and modernize the law that protects federal whistleblowers. "Not only is it a national disgrace that speaking out about wrongdoing in government is still such a risky endeavor, it also is unsustainable. Federal spending is at unprecedented levels, and the need for strict accountability and oversight has never been more urgent," Canterbury said. "Whether the issue is stimulus spending, fraud at a Wall Street firm, prescription drug safety, environmental protection or national defense, federal workers must be empowered to safeguard the public trust." In 2007, the Ethics Resource Center found that more than half the federal workforce observed misconduct on the job, but only one-quarter of those reported wrongdoing because the rest feared retaliation. More than one in 10 who did report experienced retaliation.

Environmentalists who see this year as their best hope for a major global warming bill can't seem to escape a familiar foe: former Bush administration officials they fought year after year on energy and climate issues. As the House Energy and Commerce Committee debates its ambitious cap-and-trade bill, environmentalists will find James Connaughton, President George W. Bush's top environmental adviser, advocating for Constellation Energy. Karen Harbert, a top Bush Energy Department official, is now heading the energy practice at the U.S. Chamber of Commerce - a leading critic of Democratic climate change proposals. And F. Chase Hutto III, Vice President Dick Cheney's energy and environment adviser, has formed ClearView Energy Partners, aimed at helping businesses navigate climate change legislation.
