The $5 Billion Race to Build a Better Battery

Professor Donald Sadoway remembers chuckling at an e-mail in August 2009 from a woman claiming to represent Bill Gates. The world’s richest man had taken Sadoway’s Introduction to Solid State Chemistry online, the message explained. Gates wondered if he could meet the guy teaching the popular MIT course the next time the billionaire was in the Boston area, Bloomberg Markets magazine will report in its May issue.  “I thought it was a student prank,” says Sadoway, who’s spent more than a decade melting metals in search of a cheap, long-life battery that might wean the world off dirty energy. He’d almost forgotten the note when Gates’s assistant wrote again to plead for a response.   A month later, Gates and Sadoway were swapping ideas on curbing climate change in the chemist’s second-story office on the Massachusetts Institute of Technology campus. They discussed progress on batteries to help solar and wind compete with fossil fuels. Gates said to call when Sadoway was ready to start a company. “He agreed to be an angel investor,” Sadoway says. “It would have been tough without that support.”   Sadoway is ready. He and a handful of scientists with young companies and big backers say they have a shot at solving a vexing problem: how to store and deliver power around the clock so sustainable energies can become viable alternatives to fossil fuels.  How these storage projects are allowing utility power customers to defect from the grid is one of the topics for debate this week at the Bloomberg New Energy Finance conference in New York. Today’s nickel-cadmium and lithium-ion offerings aren’t up to the task. They can’t run a home for more than a few hours or most cars for more than 100 miles (160 kilometers). At about $400 per kilowatt-hour, they’re double the price analysts say will unleash widespread green power. “Developing a storage system beyond lithium-ion is critical to unlocking the value of electric vehicles and renewable energy,” says Andrew Chung, a partner at Menlo Park, California–based venture capital firm Khosla Ventures.

In The Midst Of Toxic Oil Spill, Vancouver Announces It Will Go 100 Percent Renewable

There’s some mixed news coming out of Vancouver, Canada this week. On the one hand, the city announced at an international sustainability summit that it would commit to using 100 percent renewable energy to power its electricity, transportation, heating and air conditioning within 20 years. On the other hand, Vancouver is also dealing with a fuel spill in the waters of English Bay that is washing up on beaches and threatening wildlife. On March 26, Vancouver’s city council voted unanimously to approve Mayor Gregor Robertson motion calling for a long-term commitment to deriving all of the city’s energy from renewable sources. At the ICLEI World Congress 2015 this week in Seoul, South Korea, the city went a step further, committing to reaching that goal of 100 percent renewable electricity, transportation, heating and air conditioning by 2030 or 2035. Right now, Vancouver gets 32 percent of its energy — that includes electricity, transportation, heating, and cooling — from renewable sources, so the goal is ambitious, but not impossible. According to the Guardian, Vancouver could get all of its electricity from renewables within a few years, but transportation, heating, and cooling may prove more difficult.

Wind Power Creates 30,000 Texas Jobs, Generates $85 million in Taxes

The boom in West Texas wind-powered electricity generation has delivered a major economic boost to the region, including creation of over 40 new businesses and 30,000 construction jobs in 57 West Texas counties since 2001, according to data collected by Public Citizen’s Texas office.   The 40 new manufacturers and businesses make everything from wind turbine blades and steel towers to electronics, according to the data. Wind farms also generate over $85 million in taxes annually in rural Texas counties and more than $9 billion in new taxable assets in the last 14 years.   Over a five-month period in 2014 and 2015, Public Citizen’s Texas office collected data on the economic impact of wind development from county appraisers and tax assessors in the 57 West Texas counties. The data includes estimates of investment values, employment, tax revenues, and lease payments by wind farms, and it reflects review of previous research and case studies.

As California Faces Record Drought Levels, Wind Energy Provides A Vital Service

In 2014, wind energy saved 2.5 billion gallons of water in California by displacing water consumption at the state's fossil-fired power plants, playing a valuable role in alleviating the state's record drought. Wind energy's annual water savings work out to around 65 gallons per person in the state - or the equivalent of 20 billion bottles of water, according to the American Wind Energy Association (AWEA).   According to AWEA, one of wind energy's most overlooked benefits is that it requires virtually no water to produce electricity while almost all other electricity sources evaporate tremendous amounts of water.   In California - where the state is combating record drought levels - Gov. Jerry Brown recently signed an executive order to reduce household water consumption by 25%, from about 140 gallons per day per household to 105 gallons. Wind energy's water savings are, therefore, equivalent to what would be saved by nearly one week's worth of the required reductions for a typical household.   In 2008, U.S. thermal power plants withdrew 22 trillion to 62 trillion gallons of freshwater from rivers, lakes, streams and aquifers and consumed 1 trillion to 2 trillion gallons. By displacing generation from these conventional power plants, U.S. wind energy currently saves around 35 billion gallons of water per year - the equivalent of 120 gallons per person or 285 billion bottles of water.

California first state to generate more than 5% of electricity from utility-scale solar

All of the top 10 states-with the exception of Florida-have a renewable portfolio standard in place. Most of those policies include a specific target for solar power or customer-sited generation.

Obama wants to train 75,000 new solar workers by 2020

President Obama launch a new initiative to expand the nation’s solar industry workforce during a visit to Utah’s Hill Air Force Base on Friday, seeking to gain support for his economic agenda in a heavily-Republican state.   The Energy Department will seek to train 75,000 people — including veterans — to enter the solar workforce by 2020, increasing the goal it set in May 2014 by 25,000.   “We’ve got to be relentless in our work to grow the economy and create good jobs,” Obama said after touring the brief tour, adding that other nations are seeking to expand their economies as well. “And that’s why we have to redouble our efforts to make sure that we’re competitive, to make sure that we’re taking the steps that are needed for us to be successful.”

Retrofitting Buildings to Improve Energy Efficiency

Making a building more sustainable while completing the retrofit could attract more higher-paying tenants, which would cause a greater appreciation by the time the owners plan to sell. Properties with Energy Star certification have sold for 2-5% more than buildings without such certification.
