MIT Plan for Action on Climate Change

On October 21st the Massachusetts Institute of Technology (MIT) issued its Plan for Action on Climate Change. This document was the culmination of a year of discussions within the MIT community on the risks of climate change and the role that MIT should play as a leader on climate sciences and energy innovation. MIT’s position is that overwhelming evidence shows that the world is warmer than it was in the pre-industrial age, and that present-day climate change is due to human activity, in particular the emission of greenhouse gasses. MIT supports the 2C Challenge which aims to limit warming to 2 degrees Celsius above pre-industrial levels and sees the need for a world-wide, aggressive but pragmatic transition plan to achieve a zero-carbon energy system.

Senate approves MOX funding, but future remains cloudy

Most of the energy news recently has been focused on renewables, particularly solar and wind, which makes it particularly interesting when a different energy source makes the headlines. This article regarding the MOX (Mixed Oxide) fuel fabrication plant, currently under construction in South Carolina, addresses a relatively obscure offshoot of the topic of nuclear power, that of fuel reprocessing. What makes it triply interesting is that it has geopolitical ramifications with regard to a 2000 treaty between the US and Russia to dispose of weapons-grade plutonium and also illustrates how incredibly complicated and expensive it is to do anything with the word “nuclear” in it. Continue reading Senate approves MOX funding, but future remains cloudy

California – 50% renewable energy by 2030

On Wednesday California’s Governor Jerry Brown dramatically increased California’s climate-change goals by signing a bill that commits the state to use renewable energy for half its electricity and make existing buildings twice as energy-efficient by 2030. California already has some of the world’s toughest air quality standards, and in 2006, under Governor Arnold Schwartzenegger, mandated that renewable energy should make up one-third of its electricity by 2020. The state is well on its way to meet that goal with 25% of electricity coming from renewables last year, driven by significant increases in solar and wind power.  Continue reading California – 50% renewable energy by 2030

Texas’ Luminant to Purchase 116 MW Of Utility-Scale Solar

In an announcement made on September 8th, Luminant has agreed to buy 116 megawatts  of solar power from SunEdison’s new 800-acre Castle Gap solar facility in West Texas. Luminant is the largest generator of electricity in Texas and had total generating capacity at the end of 2014 of 15.4 GW, including coal, nuclear, and natural gas powered electrical generating plants. Total generation for 2014 was approximately 75% from coal and 25% from nuclear. Luminant is also one of the largest utility purchasers of wind power in the United States with approximately 700 MW of wind power under contract in 2014.

Shell Abandons Arctic Exploration

The oil industry has taken a number of huge hits this year with the collapse of oil prices. The latest is the announcement from Royal Dutch Shell that they are abandoning their Arctic drilling program in the Chukchi Sea off the coast of northwest Alaska after years of effort, over $7 billion spent, numerous regulatory battles, and unrelenting challenges from environmental groups. Shell announced that they found indications of oil and gas, but that they weren’t sufficient to warrant further exploration in the so-called  Burger prospect. The well will be plugged  and abandoned in accordance with U.S. regulations. The problem is that geologists believe the Arctic holds a quarter of the world’s undiscovered conventional oil and gas reserves. Shell’s high profile failure likely means that other companies won’t make similar attempts, and this resource will be unavailable to meet both US and world demand for oil  that is expected to grow by another 10% over the next several decades.

California Valley Fire Damages Geysers Geothermal Plant

One more casualty of the severe drought that has triggered devastating wildfires in California is the Geysers geothermal power generation facility, which is located on the Sonoma County and Lake County border. The Geysers is the world’s largest geothermal power production operation with a fleet of 14 power plants owned and operated by Calpine Corporation and a net operating capacity of approximately 725 megawatts. Continue reading California Valley Fire Damages Geysers Geothermal Plant

Eni Discovers Massive Gas Field in the Mediterranean

On August 30th, Eni SpA, the Italian oil company, reported discovery of a “super giant” natural gas field offshore Egypt that may be the largest find in the Mediterranean Sea and may hold hold 30 trillion cubic feet of gas. The field will go a long way toward addressing Egyptian domestic demand, which has swelled over the past years. The country is consuming most of its production and has cut gas sales abroad. Excess gas could be shipped to Italy or other destinations as liquefied natural gas (LNG) through a plant at Damietta on the Mediterranean coast that is currently not operating for lack of gas. Continue reading Eni Discovers Massive Gas Field in the Mediterranean

Drilling for wind in Lake Erie

In another small but important step forward for offshore wind development in the United States, the Lake Erie Energy Development Corp., or LEEDCo, began testing the soils at the bottom of Lake Erie. The tests and drilling for soil samples are being done at the six sites where LEEDCo has proposed locating turbines for an offshore wind pilot project. The sites are eight to 10 miles offshore, northwest of downtown Cleveland. Results will help answer the question of what kind of soil lies below the sandy lake bottom and will enable engineers to design the foundations for the turbines.

First OTEC Plant Connected to US Grid

On August 21st a dedication ceremony at the Natural Energy Laboratory of Hawaii Authority in Kona was held to celebrate completion of the world’s largest operational ocean thermal energy conversion (OTEC) power plant. This was a major achievement for Hawaii, the U.S. and marine renewable energy. This test plant will generate 100 kilowatts of clean, continuous, sustainable electricity and is expected to be a stepping stone to larger plants that will be cost competitive options for electrical power for Hawaii and other island locations in Asia Pacific

OTEC uses the temperature difference between deep cold ocean water and warm surface water to boil liquid ammonia, which can then drive a turbine to generate electricity. It is estimated that ocean thermal energy conversion has the potential to generate over four times the total electricity usage of the planet.

New Solar Project Announcements

The past several months have brought a number of very positive announcements concerning new, utility scale, solar projects in three different Western states. Just yesterday SunEdison Inc. announced that it has begun construction on the 156-megawatt Comanche solar farm in Colorado, which will be the largest in the state. It will deliver power to Excel Energy Inc.’s Public Service of Colorado utility under a 25-year agreement. The plant will help Colorado meet its requirement per 2010 law that investor-owned utilities get 30 percent of their power from renewable sources by 2020.

This announcement comes on the heels of two other solar project announcements in July: 1) start of construction on the 137 megawatt (MW) Springbok 1 Solar project about 70 miles north of Los Angeles, and 2) signing by SunPower of a 20-year Power Purchase Agreement (PPA) with NV Energy in Nevada to build a 100 MW solar PV power plant near Boulder City, Nevada.

And finally, two announcements in June: 1) The Solar Star solar power plant, also located north of Los Angeles near Rosamond, California, with a total capacity of 579 MW, went fully online on June 19, 2015, making it the largest solar power plant in the world, and 2) SunPower has commenced construction of the 102 MW Henrietta solar power plant in Kings County, California.
