We Can Win the Fight Against Climate Change

The United States can deliver 90 percent clean, carbon-free electricity nationwide by 2035, dependably, at no extra cost to consumers and without the need for new fossil fuel plants, according to 2035 Report: Plummeting Solar, Wind, and Battery Costs Can Accelerate Our Clean Energy Future, a study released in June from the University of California, Berkeley.

The 2035 Report is the first study of its kind to show how recent cost declines for solar, wind, and battery storage allow the U.S. to dramatically reduce generation and emissions from existing fossil power plants while retiring coal and reducing gas generation by 70 percent.

Economic & Job Growth

The rapid buildout of additional renewable energy would inject $1.7 trillion of investment into the economy and increase energy sector jobs by up to 530,000 per year through 2035, across all regions of the U.S., without raising consumer bills.

The 2035 Report’s release is accompanied by a set of policy recommendations to realize the jobs and economic benefits envisioned by the nonpartisan policy firm Energy Innovation. The primary policy recommendation is establishing a technology-neutral national clean energy standard targeting 90 percent by 2035 and 100 percent by 2045. Additional recommendations to unlock a clean energy future include complementary policies that support clean energy deployment, address wholesale market failures, remake utility grid regulation, and ensure an equitable and fair energy transition for impacted communities.

“What an incredible opportunity for economic stimulus. A federal clean energy standard, supported by government investments in deployment and American manufacturing, could put us back on track for a healthier economy. Meanwhile, continued policy leadership from the states can bolster progress.”

―Sonia Aggarwal, Vice President at Energy Innovation

Path to Avoid Worst Climate Change Impacts

The 2035 time frame for near-complete decarbonization of the power sector is significant because it is 15 years earlier than projected in most state and national policy proposals, which provide little hope that the worst climate change impacts can be avoided. In October 2018, the U.N.’s Intergovernmental Panel on Climate Change warned that the world has only a dozen years to halve emissions in order to limit warming to 1.5°C.

“We’re talking about the ability to achieve near-100 percent clean electricity by 2035, in half the time most people are talking about.”

“This is exciting, because the 2035 timeframe is actually compatible with climate realities. However, this outcome isn’t possible without strong policy changes and our hope is this report can help inform the dialogue on federal, state, and corporate policies needed to achieve it.”

―David Wooley, professor at the UC Berkeley Goldman School of Public Policy and Executive Director of the Center for Environmental Public Policy

By 2030, the report finds the U.S. could reach over 70 percent clean electricity, reducing U.S. economy-wide emissions by 18 percent. Up to 85,000 unnecessary premature deaths associated with air pollution from power plants in the U.S. could be avoided through 2050 by reaching a 90 percent carbon-free electric generation sector by 2035, which would reduce economy-wide emissions 27 percent.

Savings & Reduced Damage from Pollution

Delivering 90 percent clean electricity by 2035 also avoids $1.2 trillion in environmental and health costs through 2050 by reducing damages from air pollution and carbon emissions.

The target year of 2035 allows sufficient time for most coal and gas plants to recover their fixed costs, thereby avoiding risk of stranded costs for consumers and investors, if the right policies are in place.

“Cost reductions in clean technology have occurred much faster than anticipated just a few years ago.”

“This is the first report to integrate the latest low prices for renewable energy and storage and shows it is technically and economically feasible to deliver 90 percent carbon-free electricity on the U.S. power grid by 2035.”

―Dr. Amol Phadke, Senior Scientist and affiliate at UC Berkeley’s Center for Environmental Public Policy

New fossil fuel generators are not needed. Wind, solar, and battery storage can provide the bulk of the 90 percent clean electricity. Existing gas plants used infrequently and combined with storage, hydropower, and nuclear power are sufficient to meet demand during periods of extraordinarily low renewable energy generation or exceptionally high electricity demand. Power generation from natural gas plants would drop by 70 percent in 2035 compared to 2019.

The study also finds that robust policy reforms are needed to reduce emissions and increase jobs will not be realized.

Internet Data Centers & Energy-Efficiency

Internet data centers are fast becoming the largest power hogs in the world. What’s being done in this industry to make Internet usage more energy-efficient?

Though our online activity uses no paper, it still consumes quite a lot of energy. Data centers account for much of this energy use. These warehouse-sized buildings contain arrays or “farms” of servers, which are essentially souped-up computers that have many uses, including storing data and supporting all the activity on the internet. They are the hardware behind the proverbial “cloud.”

Like the personal computers we all use, servers require electricity to function. Since internet users can call upon them to provide information at any time, they must remain on 24/7. Furthermore, as with any form of electrical activity, the functioning of this large number of servers packed together in a small area can result in overheating, making the need for cooling an additional energy cost for data center managers.

According to data center provider vXchnge, U.S. data centers alone use over 90 billion kilowatt-hours of electricity annually—about what 34 coal-powered plants generating 500 megawatts each produce. ComputerWorld magazine reports that the energy consumption of data centers worldwide will likely account for 3.2 percent of global carbon emissions by 2025—about as much as the airline industry—and as much as 14 percent by 2040.

In light of all this, finding ways to cut energy use has become a big priority in the industry. One of the simplest strategies is to locate data centers in cool climates, and use outdoor air to counter excessive heating. Alternate options include cooling inlet air by running it underground, or using a nearby water source for liquid cooling. Another issue is separating hot air produced by servers from the colder air used to cool them—no easy task if the servers are all housed together. But there are plenty of cheap solutions. Google, for example, uses low cost dividers from meat lockers for this purpose.

Another way data centers can reduce cooling costs is to design servers that can operate at high temperatures without overheating. Recent research shows that servers can operate at much higher temperatures than initially believed without compromising safety or efficiency. But not all data centers are comfortable letting their servers run hot. Other ways to make server farms more efficient include optimizing grid-to-server electrical conversions and reducing the energy required by “sleeping” servers.

The good news is the industry is making strides in the right direction. Apple, Facebook and Google all power 100 percent of their data center and other operations with renewables, albeit through the purchase of “renewable energy credits” akin to carbon offsets that air travelers can buy to keep their carbon footprints in check. Microsoft is moving toward 70 percent renewable energy by 2023, while laggard Amazon still only gets about half its data center power from renewables. And Switch, one of the largest U.S.-based data center companies, transitioned all of its facilities to run on nothing but renewables in 2016, including the nation’s largest data center in Reno, Nevada.
