Tesla Battery Can Boost Renewables, Helping Phase Out Nuclear

Nukewatch Quarterly Spring 2015
Energy Analysis

Though the transition from nuclear- and fossil-fueled to renewable electricity sources has the potential to address two imminent catastrophes facing the human race—radioactive contamination and climate change—several hurdles have stood in the way of a full-out energy revolution. Soon, Tesla Motors, Inc. may be breaking one of these barriers, unveiling new battery technology that allows for efficient storage of energy produced by renewable technologies—such as photovoltaic solar collectors and wind turbines.

On February 11, Tesla CEO Elon Musk announced the company’s new project in a conference call. “We are going to unveil the Tesla home battery, the consumer battery that would be for use in people’s houses or businesses fairly soon,” Musk said.

Musk added that he expected to introduce the new battery within two months. “We have the design done, and it should start going into production in about six months or so.”

Already known for its all-electric Model S sedan, Tesla is an established leader in lithium-ion battery technology. Musk is also the chairperson of SolarCity, which has successfully pioneered a residential rooftop solar installation strategy that allows people to lease photovoltaic panels for less than their regular electricity bill. Musk has promised that residential SolarCity units would come with battery storage within five to 10 years, enabling customers to more easily live “off-grid.” This kind of solar power, he said, would be cheaper than natural gas (and thus much cheaper than nuclear, which is struggling to cut costs in the face of booms in “fracking” gas extraction and clean energy).

Enabling the average homeowner to access viable electricity through a combination of rooftop solar power and efficient battery storage could pose a major threat to electric utilities, which have been slow to move away from “base load” power sources like coal and nuclear. Production facilities that use these dirty fuels are slow to start up and shut down, meaning they’re not compatible with more intermittently-produced renewable sources on an electric grid. Efficient energy storage, like a Tesla battery, could put the final nail in the coffin of archaic base load electricity generators.

Some utilities and states have adopted a process of “net metering,” which allows producers of home solar and wind power to sell excess electricity back through the grid. (The Nukewatch office and the Plowshares Land Trust is now electrified this way using the 10,000 watt, grid-tied solar panel system we installed in 2013.])

Others—motivated by nuclear industry lobbyists to artificially make nuclear power appear competitively priced—are causing outrage among their customers by trying to lower the rates at which they buy net-metered renewable energy or even fully eliminating net-metering. With new battery storage technology, these customers could have the option of walking away from their utilities altogether.

But many experts have argued that renewable energy production and storage will work most efficiently on a grid of significant scale, with many distributed production sources, flexible storage options, and consumer-level efficiencies. There is a role for utilities in this emerging energy system, if they are able to adapt quickly enough to fill it. Both Tesla and SolarCity do extensive outreach to existing utilities. But there is no role for nuclear or coal-based power—at least not within a society that values its own well-being.

Some may question whether a market-based corporate technology can really solve our energy problems, which arguably have been caused by the greed of other corporations (along with the failure of public policy to regulate them). Indeed, if their common vision is realized, Tesla and SolarCity will largely control markets for electricity-producing solar panels, the batteries that regulate energy storage, and the electric cars powered by renewable electricity. But in the face of a nuclear industry that insists on operating its aging reactors at full capacity even in the wake of a global disaster like the one at Fukushima—not to mention a fossil fuel industry that is irreversibly destroying our planet’s ecosystem through climate change—the rise of a dominant renewable energy industry might feel like a breath of fresh air.

Vermont’s Largest Municipal Utility Goes 100-Percent Renewable 

Nukewatch Quarterly Winter 2014

Vermont may be best known for maple syrup and Ben & Jerry’s ice cream, but now its largest city can boast another accomplishment. The city of Burlington (pop. 42,000) now gets 100 percent of its electricity from renewable sources. The Burlington Electric Department (BED) is the state’s largest municipal utility. Wind, hydro and biomass provide most of the city’s electricity, along with some fossil-fueled generation that comes via short-term contracts from the greater New England grid, which BED offsets with renewable energy credit purchases.

Now, with BED’s recent purchase of a nearby 7.4 megawatt hydroelectric project early in September, Burlington is 100 percent renewable. “This has been a goal of BED for over a decade, so we are excited to finally reach [it],” Mary Sullivan, communications coordinator for BED, told the Rocky Mountain Institute.

The Burlington Initiative is part of Vermont’s goal to produce 90 percent of its energy from renewable resources by 2050, including electricity, heating, and transportation.

Renewables Overtake Nuclear as Scotland’s Top Electric Power Source 

Nukewatch Quarterly Winter 2014

Clean energy produced more electricity in Scotland than nuclear, coal or gas for the first time, in the first half of 2014. Renewable energy in Scotland from wind farms, hydro power and other clean systems provided the single largest source of electricity to the country for the first time, new industry figures showed.

Analysis by the trade body Scottish Renewables showed that renewables produced nearly one third more power than nuclear, coal or gas in the first six months of 2014, generating a record 10.4 terawatt hours during the six-month period. A terawatt is a trillion watts.

The analysis compared Energy Trends data on renewable energy output produced by the Department of Energy and Climate Change, with figures produced by the national grid on coal, gas and nuclear power.

Niall Stuart, Chief Executive of Scottish Renewables, said the record figures marked a major leap forward for the government’s plan to generate 100 percent of its electricity from renewable sources by 2020.

“This important milestone is good news for anyone who cares about Scotland’s economy, our energy security and our efforts to tackle climate change,” Stuart said.

Onshore wind and hydro power remain Scotland’s main sources of renewable energy, but Stuart said there is significant potential for offshore wind and wave and tidal power if they receive sufficient government support, including new grid connections to Scottish islands.

Scotland’s Business, Energy and Tourism Minister, Fergus Ewing, said the figures highlight the potential that renewable energy has to replace nuclear power.

Netherlands Tests Roadway  Solar Collectors 

Nukewatch Quarterly Winter 2014

“SolaRoad,” a project that tests road surfaces as a means of collecting solar energy, started in November in Holland with 230 feet of a bike path in the town of Krommenie, near Amsterdam.

The path is built of Lego-like solar panels set in concrete and shielded with glass. Sten de Wit of the engineering firm TNO said Nov. 11 that every square meter of road generated 50 to 70 kilowatt-hours of energy per year, or enough for the initial strip to supply power to one or two Dutch households. The test is scheduled to run for three years and cost 3 million euros or about $3.7 million. Mr. De Wit said successor projects may be even more profitable as solar cells grow cheaper and more efficient.

International Nuclear Power Fading Fast, Study Finds 

Nukewatch Quarterly Fall 2014

The latest World Nuclear Industry Status Report, published in July 2014,* provides a comprehensive review of nuclear power data, which “is critically important to understanding the past and current situations without bias for a healthy public policy debate.” According to the study’s forward by Tatsujiro Suzuki — who until March 2014 was Vice-Chairman of the Japan Atomic Energy Commission and is one of the report’s eight authors. 

The collage “Unsinkable,” by Chris Jordan, is made up of 67,000 photos of mushroom clouds, equal to the number of metric tons of ultra-radioactive waste being stored in temporary on-site pools at the US’s 100 operating reactors. A closer view o f the art is available at www.chrisjordan.com.

The report includes information on reactor operations, production and construction and looks extensively at the status of new-build programs in existing as well as in potential newcomer countries, considering in detail how changing market conditions are affecting the economics of nuclear power. The 2014 edition updates a Fukushima Status Report featured for the first time in 2013 which then triggered widespread media attention. The Nuclear Power vs. Renewable Energy chapter provides comparative data on investment, capacity and generation and assesses how nuclear power performs in systems with high renewable energy share. 

The report’s detailed country-by-country analysis provides an overview of all 31 countries operating nuclear power reactors, with extended sections on China, Japan and the United States. 

Some of the key findings by the report’s eight authors reporting from London, Paris, Berlin, Hamburg and Tokyo, include: 

• A declining role. Nuclear power’s share of global commercial primary energy production declined from the 2012 low of 4.5 percent, a level last seen in 1984, to a new low of 4.4 percent. 

• Aging machinery. The average age of the world’s operating nuclear reactors is increasing and by mid-2014 stood at 28.5 years. 

• Construction delays. At least 49 of the total of 69 construction sites — including three quarters of the Chinese projects — have encountered delays, many of them multi-annual. Construction of two units in Taiwan was halted. 

• Project cancellations. Several projects have been cancelled and new programs indefinitely delayed, including in the Czech Republic and in Vietnam. 

• Operating costs soar. Nuclear reactor generating costs jumped 16 percent in real terms in three years in France, and several units were shut down in the US because income does not cover operating costs. The economic survival of nuclear reactors is also threatened in Belgium, Germany and Sweden. 

• Renewables trump nuclear. In 2013 alone, 32 gigawatts (GW) of wind and 37 GW of solar were added to the world power grids. By the end of 2013, China had 91 GW of wind power and 18 GW of solar capacity installed, solar exceeding operating nuclear capacity for the first time. China added four times more solar than nuclear reactor capacity in the past year, and Spain generated more power from wind than from any other source, outpacing nuclear for the first time. Also the first time in any country, Spain made wind the largest electricity generating source over an entire year. Spain has thus joined the list of reactor operating countries that produce more electricity from new renewables — excluding large hydro-power — than from its nuclear reactors. The others are Brazil, China, Germany, India and Japan.
