Prepare to be Electrified

April 14, 2019 I'd never heard of the International Renewable Energy Agency (IRENA) before, but the 160 countries and regional intergovernmental agencies that comprise its membership have released a report entitled Global Energy Transformation: A Roadmap to 2050. I ran across a summary of the report at Think Progress, and I thought I'd share parts of it with you. This is an important report. The members of IRENA base their research on the premise that renewable energy sources, as the most accessible energy on earth, can accelerate conversion to electricity on a global scale while meeting agreed-upon climate objectives. (I should mention that member countries must also belong to the United Nations.) Their report maintains that because prices of key clean energy technologies are dropping, as much as 85% of the world's energy could come from renewable energy sources, primarily solar and wind. Keeping the global temperature increase below two degrees Celsius, or 3.6 degrees...

A Carbon-Free Grid

March 3, 2018 - Scientists at the University Of California, Irvine; the California Institute of Technology; and the Carnegie Institution of Science recently published an article stating that the United States could meet 80 percent of its electricity needs with solar and wind power. To sweeten the deal, the price of solar and wind have been dropping rapidly. The remaining 20 percent could be provided by alternate sources of energy such as hydropower, geothermal, and biomass. These sources currently meet 8.5 percent of electrical demand, and can be expanded. The remaining deficit would be met by managing demand. The larger grid required for transmission of solar and wind power would have to be continental in scale, or 12 hours' worth of the energy would have to be stored in new facilities. This degree of expansion would require hundreds of billions of dollars in investment. Storing the electricity with today's cheapest batteries would cost a trillion dollars, although the price...

Michiganders Like It Windy

August 20, 2012 - You know, it's hard to decide what to write about these days.  Climate extremes are happening all the time now, and I don't ever want to treat what people are going through as if it were unimportant.  On the other hand, it's very easy to tell what my readers like, and want: you guys want to hear some good news.  Last week's blog article was the most popular I've ever written, bar none.  So this week I'm going to mix it up.  First, let's all admit that it's impossible to ignore the fires burning in the western United States. I know - they're getting a lot of coverage, and it's pretty scary stuff.  There's nothing I can say to make the situation less horrible than it is.  We all want so very badly for the fires to just stop burning!  Fact is, dead trees as dry as tinder are always going to catch fire when they're struck by lightning.  This is a good time to remind ourselves of one of those basic facts of life: we c...

Changing Climate, Changing World

May 9, 2011 – A very important report was issued by the IPCC (Intergovernmental Panel on Climate Change) today. The 2200 member scientists of the U.N.-sponsored organization have found renewable energy sources to hold the key to the future. (We might actually have one if we use them!) The report targets 450 ppm of greenhouse gases as the upper limit, beyond which life as we know it would not be sustainable. This level of GHG concentration exceeds the more ideal level of 350 ppm considerably, perhaps a tacit admission on the part of the report’s authors that they no longer think the lower concentration is achievable. The IPCC believes that 80% of the world’s energy needs can be met by renewable energy sources, and that the financial investment required would amount to only 1% of GDP, or approximately five trillion dollars over the next decade. The very plain implication of such numbers is that failure to make the small investment needed would be nothing short of criminal. The lack of fo...
October 26, 2009 – I’d like to review a very important book today. Brown, Lester. Plan B 4.0: Mobilizing to Save Civilization. New York: W.W. Norton & Co. 2009. Before I do, allow me to correct a misstatement in a previous article. I believe I erroneously referred to Brown as one of the “unsung” heroes of the environmental movement. That, as it turns out, is rather far left of the truth. I’ll quote directly from the dust jacket of this book: “Lester R. Brown is the president of Earth Policy Institute, an organization dedicated to building a sustainable future. Described by the Washington Post as ‘one of the world’s most influential thinkers,’ Brown started his career as a tomato farmer. Shortly after earning a degree in agricultural science, he spent six months living in rural India, where he became intimately familiar with the food/population issue. Brown later became head of the U.S. Department of Agriculture’s International Agricultural Development Service. In 1974, he fo...
