Despite the Trump administration's ongoing attempts to prop up coal and undermine renewables—at FERC, EPA and through tariffs and the budget process—2018 should instead be remembered for the surge in momentum toward a clean energy economy. Here are nine storylines that caught my attention this past year and help illustrate the unstoppable advancement of renewable energy and other modern grid technologies.
1. California Goes All-In for Carbon-Free Electricity
In late August, California—the world's 5th largest economy—committed to the target of fully decarbonizing its power sector by 2045. The landmark legislation also strengthens the state's renewable portfolio standard (also known as a renewable energy standard, or RES) from 50 to 60 percent by 2030. What's more, at the bill signing, Governor Jerry Brown signed an executive order that establishes a goal of achieving carbon-neutrality across all sectors of California's sprawling economy by 2045, cementing the state's place as a global leader in climate action.
2. Several States Strengthen Their RES Requirements
State-level renewable electricity standards continued to be a primary driver of new renewable energy development in 2018. In addition to California, legislatures in New Jersey (50 percent by 2030), Connecticut (40 percent by 2030) and Massachusetts (35 percent by 2030) all adopted stronger targets for renewable energy, accelerating their states' transitions away from fossil fuels. In addition, voters in Nevada overwhelmingly approved a measure to increase their state's RES to 50 percent by 2030 (the measure must be approved again in 2020 to officially become law).
3. Clean Energy Champions Win Gubernatorial Races
One of the bright spots in November's election results was the number newly elected governors who campaigned on aggressive clean energy and climate change agendas. Newly elected governors in at least 10 states, including California, Colorado, Connecticut, Illinois, Maine, Michigan, Minnesota, Nevada, New Mexico and Wisconsin, have pledged to accelerate clean energy and carbon reductions in their states by supporting U.S. commitments to the Paris agreement, joining the U.S. Climate Alliance and/or calling for renewable energy targets of 80 to 100 percent. These election results demonstrate the widespread support for greater investments in renewable energy and signal the push for even stronger clean energy policies in the coming year.
4. Record Low Prices for Renewables
Innovation, growing economies of scale and attractive financing continued to drive the costs down for renewables in 2018. Power purchase agreements for wind and solar projects in states like Arizona, Nevada, Colorado, Kansas, New Mexico, Oklahoma and Texas have reportedly ranged between $20 to $30 per megawatt-hour, well below the cost of natural gas generation—and the technologies are positioned for further cost reductions to continue to be low-cost options even as federal tax incentives change. What's even more exciting is that the many of these low-priced projects also include energy storage components, increasing their value to the grid.
5. Major Utilities Commit to Low-Carbon Portfolios
Earlier this month, Xcel Energy became the first major utility to commit to a completely carbon-free electricity supply across the eight states it operates in. In doing so, it joins a growing number of utilities that are committing to phasing out their use of coal and transitioning to substantially lower carbon energy portfolios. Also this year, both Consumers Energy in Michigan and NIPSCO in northern Indiana announced plans to phase out coal generation and utility giant American Electric Power announced a goal of reducing its carbon emissions 80 percent by 2050. What's especially exciting about these utility actions is that they are driven primarily by economics, clearly demonstrating the competitiveness of clean energy technologies.
6. Corporate Renewable Energy Purchases Keep Growing
Low renewable energy prices continue to attract major corporations looking to save money and achieve ambitious sustainability goals. As a result, direct corporate purchases of renewable energy have become a major driver of renewable energy deployment. In 2018, the Rocky Mountain Institute reports, corporate renewable energy purchases—led by companies like Facebook, Walmart, ATT and Microsoft—reached more than 6.4 gigawatts (GW). The number of corporations investing in renewables expanded at a record pace this year as well, with nearly two-thirds of Fortune 100 and nearly half of Fortune 500 companies now having set ambitious renewable energy goals.
7. Offshore Wind Moves Forward
While no new offshore wind projects came online in the U.S. this year (the next project—off the Virginia coast—is scheduled for 2020), the industry did take some big leaps toward becoming a major player in the nation's power supply. For example, the winning bid for Massachusetts' first request for offshore wind proposals to help meet the state's offshore wind requirements passed in 2016 went to an 800-megawatt project from Vineyard Wind at a shockingly low price of about 6.5 cents per kilowatt-hour. In addition, the latest U.S. Bureau of Ocean Energy Management auction for leasing parcels of water for future projects resulted in 11 bidders and $405.1 million in winning bids, both smashing previous records. And strong state policies, including new offshore wind requirements in New Jersey and elsewhere, mean that there's a lot more action to come.
8. Storage Steps Into the Spotlight
Once a fringe player in the electric power sector, the energy storage industry is quickly emerging as a game changer in the transition to a clean energy economy as a tool for integrating much higher levels of renewable energy. In 2018, the pipeline for new storage projects doubled to nearly 33 GW as more utilities are investing in the technology thanks largely rapidly falling prices and growing support from state policies. While California has led the nation in storage deployment to date, New York recently established the strongest storage requirement in the country at 3,000 MW by 2030. Earlier this year, New Jersey set an ambitious storage target of 2,000 MW by 2030 and Massachusetts significantly increased its storage requirement to 1,000 megawatt-hours by 2025. At the federal level, the Federal Energy Regulatory Commission issued Order 841, which directs regional grid operators to set market rules that allow energy storage to participate on a level playing field in the wholesale energy, capacity and ancillary services markets.
9. PG&E Turns Down the Gas With Storage and Renewables
In one particular sign of what's to come in 2019 and beyond in terms of how these technologies fit together to displace fossil fuels, one of the most exciting regulatory decisions I saw this year was the California Public Utility Commission's approval of PG&E's plan to use energy storage to replace retiring gas generators. One of the key barriers to fully transitioning to a carbon-free economy is replacing natural gas generation and the ancillary services they provide to the power grid. This decision, which marks the first time a utility will directly replace power plants with battery storage, should spur many more similar projects to move forward in California and across the country and open the door for integrating much higher levels of renewable energy onto the power grid.
These nine stories are just a sampling of what occurred in 2018 to further the clean energy transition. As the year comes to a close, UCS will continue to work hard to keep up the clean energy momentum in 2019.

Jeff Deyette is the director of state policy and analysis at the Union of Concerned Scientists.
Though made in large part of plastic, glass, ceramics, gold and copper, they also contain critical resources. The gallium used for LEDs and the camera flash, the tantalum in capacitors and indium that powers the display were all pulled from the ground — at a price for nature and people.
"Mining raw materials is always problematic, both with regard to human rights and ecology," said Melanie Müller, raw materials expert of the German think tank SWP. "Their production process is pretty toxic."
The gallium and indium in many phones comes from China or South Korea, the tantalum from the Democratic Republic of Congo or Rwanda. All in, such materials comprise less than ten grams of a phone's weight. But these grams finance an international mining industry that causes radioactive earth dumps, poisoned groundwater and Indigenous population displacement.
Environmental Damage: 'Nature Has Been Overexploited'
The problem is that modern technologies don't work without what are known as critical raw materials. Collectively, solar panels, drones, 3D printers and smartphone contain as many as 30 of these different elements sourced from around the globe. A prime example is lithium from Chile, which is essential in the manufacture of batteries for electric vehicles.
"No one, not even within the industry, would deny that mining lithium causes enormous environmental damage," Müller explained, in reference to the artificial lakes companies create when flushing the metal out of underground brine reservoirs. "The process uses vast amounts of water, so you end up with these huge flooded areas where the lithium settles."
This means of extraction results in the destruction and contamination of the natural water system. Unique plants and animals lose access to groundwater and watering holes. There have also been reports of freshwater becoming salinated due to extensive acidic waste water during lithium mining.
But lithium is not the only raw material that causes damage. Securing just one ton of rare earth elements produces 2,000 tons of toxic waste, and has devastated large regions of China, said Günther Hilpert, head of the Asia Research Division of the German think tank SWP.
He says companies there have adopted a process of spraying acid over the mining areas in order to separate the rare earths from other ores, and that mined areas are often abandoned after excavation.
"They are no longer viable for agricultural use," Hilpert said. "Nature has been overexploited."
China is not the only country with low environmental mining standards and poor resource governance. In Madagascar, for example, a thriving illegal gem and metal mining sector has been linked to rainforest depletion and destruction of natural lemur habitats.
States like Madagascar, Rwanda and the DRC score poorly on the Environmental Performance Index that ranks 180 countries for their effort on factors including conservation, air quality, waste management and emissions. Environmentalists are therefore particularly concerned that these countries are mining highly toxic materials like beryllium, tantalum and cobalt.
But it is not only nature that suffers from the extraction of high-demand critical raw materials.
"It is a dirty, toxic, partly radioactive industry," Hilpert said. "China, for example, has never really cared about human rights when it comes to achieving production targets."
Dirty, Toxic, Radioactive: Working in the Mining Sector
One of the most extreme examples is Baotou, a Chinese city in Inner Mongolia, where rare earth mining poisoned surrounding farms and nearby villages, causing thousands of people to leave the area.
In 2012, The Guardian described a toxic lake created in conjunction with rare earth mining as "a murky expanse of water, in which no fish or algae can survive. The shore is coated with a black crust, so thick you can walk on it. Into this huge, 10 sq km tailings pond nearby factories discharge water loaded with chemicals used to process the 17 most sought after minerals in the world."
Local residents reported health issues including aching legs, diabetes, osteoporosis and chest problems, The Guardian wrote.
South Africa has also been held up for turning a blind eye to the health impacts of mining.
"The platinum sector in South Africa has been criticized for performing very poorly on human rights — even within the raw materials sector," Müller said.
In 2012, security forces killed 34 miners who had been protesting poor working conditions and low wages at a mine owned by the British company Lonmin. What became known as the "Marikana massacre" triggered several spontaneous strikes across the country's mining sector.
Müller says miners can still face exposure to acid drainage — a frequent byproduct of platinum mining — that can cause chemical burns and severe lung damage. Though this can be prevented by a careful waste system.
Some progress was made in 2016 when the South African government announced plans to make mining companies pay $800 million (€679 million) for recycling acid mine water. But they didn't all comply. In 2020, activists sued Australian-owned mining company Mintails and the government to cover the cost of environmental cleanup.
Another massive issue around mining is water consumption. Since the extraction of critical raw materials is very water intensive, drought prone countries such as South Africa, have witnessed an increase in conflicts over supply.
For years, industry, government and the South African public debated – without a clear agreement – whether companies should get privileged access to water and how much the population may suffer from shortages.
Mining in Brazil: Replacing Nature, People, Land Rights
Beyond the direct health and environmental impact of mining toxic substances, quarrying critical raw materials destroys livelihoods, as developments in Brazil demonstrate.
"Brazil is the major worldwide niobium producer and reserves in [the state of] Minas Gerais would last more than 200 years [at the current rate of demand]," said Juliana Siqueira-Gay, environmental engineer and Ph.D. student at the University of São Paulo.
While the overall number of niobium mining requests is stagnating, the share of claims for Indigenous land has skyrocketed from 3 to 36 percent within one year. If granted, 23 percent of the Amazon forest and the homeland of 222 Indigenous groups could fall victim to deforestation in the name of mining, a study by Siqueira-Gay finds.
In early 2020, Brazilian President Jair Bolsonaro signed a bill which would allow corporations to develop areas populated by Indigenous communities in the future. The law has not yet entered into force, but "this policy could have long-lasting negative effects on Brazil's socio-biodiversity," said Siqueira-Gay.
One example are the niobium reserves in Seis Lagos, in Brazil's northeast, which could be quarried to build electrolytic capacitors for smartphones.
"They overlap the Balaio Indigenous land and it would cause major impacts in Indigenous communities by clearing forests responsible for providing food, raw materials and regulating the local climate," Siqueira-Gay explained.
She says scientific good practice guidelines offer a blueprint for sustainable mining that adheres to human rights and protects forests. Quarries in South America — and especially Brazil — funded by multilaterial banks like the International Finance Corporation of the World Bank Group have to follow these guidelines, Siqueira-Gay said.
They force companies to develop sustainable water supply, minimize acid exposure and re-vegetate mined surfaces. "First, negative impacts must be avoided, then minimized and at last compensated — not the other way around."
