The China Global Power (CGP) Database, developed by Boston University’s Global Development Policy Center, systematically tracks power plants outside of China that are financed through Chinese foreign direct investment and its two major policy banks—the China Development Bank and the Export-Import Bank of China. As of mid-2022, China-backed investments supported 648 power plants across 171.6 […]

Driven by artificial intelligence (AI), cloud computing, and the digital transformation, U.S. data centers consumed an estimated 150 TWh of electricity in 2023—equivalent to around 3% of the nation’s power demand. Globally, data center demand hovered at 340 TWh in 2023—about 1.3% of worldwide electricity use. Multiple sources project this demand will surge dramatically through […]

According to the Global Geothermal Power Tracker (GGPT), a comprehensive dataset of geothermal power facilities, about 14 GW of geothermal power is operational worldwide. The U.S. has the largest installed capacity at 3,900 MW, followed by Indonesia (2,418 MW), the Philippines (1,952 MW), Türkiye (1,691 MW), New Zealand (1,042 MW), and Kenya (985 MW). Most […]

The U.S. conventional hydropower fleet includes 2,252 hydropower plants with a total generating capacity of 80.58 GW, which produced 6.2% of the country’s electricity in 2022 and nearly 30% of all renewable generation. In addition, it has 43 pumped-storage hydro (PSH) plants, a combined capacity of 22 GW, and an estimated energy storage capacity of 553 […]

The Global Energy Monitor (GEM), an organization dedicated to enhancing understanding of climate change data, in a recent report, estimated that about 89.6 GW (or 13%) of the 692 GW of global gas-fired capacity in development are coal-to-gas conversions or replacements. East Asia has the most coal-to-gas conversions or replacements in development (29.6 GW). By […]

The deployment of new power plants in the U.S. over the past 14 decades has hinged on policies, markets, technologies, and new industry players. Every decade has presented its own state of multidimensional, multivariate complexity. The ongoing “energy transition,” which has been characterized by the addition of smaller, carbon-free resources, marks another pivotal period in […]

The Energy Information Administration’s (EIA’s) June 2021 electric generator inventory suggests 260 battery energy storage systems (BESSs) are now operational in the U.S., representing a total nameplate capacity of 2,673 MW. Another 12,914 MW from 212 BESS projects are in various stages of planning or construction, with more than 10 GW readying to begin operations […]

The coronavirus pandemic has triggered a macroeconomic shock that is unprecedented in peacetime. By the end of the first quarter, its effects on global power demand were deep, the International Energy Agency (IEA) noted in a flagship report released on April 30. The international organization, which has collected daily data for more than 30 countries […]

Lawrence Livermore National Laboratory’s (LLNL’s) latest annual energy flow chart suggests that in 2019, for the second year in a row, wind and solar made up the largest increases in U.S. energy supply, but American consumption of energy fell after a record year in 2018. The national lab’s annual U.S. energy flow chart, or Sankey […]

According to the International Energy Agency’s (IEA’s) World Energy Outlook 2019, solar photovoltaic (PV) is set to become the largest source of installed electrical capacity in about 2035, if countries pursue policies as planned. By 2040, solar could make up 24% of global installed capacity—up from 7% in 2018—but its share of generation could hover […]

According to experts from Technical University of Applied Sciences (OTH) in Regensburg, Germany, who recently reviewed the world’s existing power-to-gas (P2G) hydrogen and methane projects, about 143 P2G projects have operated since 1988 in 22 countries. Only 56 hydrogen and 38 methanation projects were active in 2019. While the existing fleet mostly comprises pilot or […]

Hydrogen is emerging as a formidable player in the energy transition, owing to its potential to decarbonize a range of sectors and its versatility. According to a June 2019–released report prepared for the G20 by the International Energy Agency (IEA) and the government of Japan, 76% of dedicated hydrogen produced today (around 70 metric tons) […]

As of August 2019, 29 U.S. states and the District of Columbia had renewable portfolio standards (RPSs), and eight others had non-binding renewable portfolio goals. Three states also had clean energy standards, which set targets for low-carbon non-renewables, like nuclear, and two had clean energy goals. Our monthly infographic in September 2019 shows how shares for each […]

After the Great Tohoku Earthquake and tsunami, and ensuing crisis at the Fukushima Daiichi nuclear plant in March 2011, Japan issued stringent safety regulations and reviews that affected its entire 50-reactor fleet. It meant that as each Japanese nuclear reactor entered its scheduled maintenance and refueling outage, it could not returned to operation until restart […]

According to the Nuclear Regulatory Commission (NRC), the nation’s 99 operating nuclear reactors operated at an average capacity factor of 88% in 2017—the same as in 2016—despite market forces that have rendered several units uneconomical. Figures for 2018 are expected in 2019 and may look different. Oyster Creek Nuclear Station, for example, was permanently closed […]

Because the widespread adoption of electric vehicles (EVs) could ramp up demand for electricity and slash transportation-related emissions of carbon dioxide and other pollutants, a growing group of stakeholders, including power companies and trade groups, strongly advocate for an accelerated EV rollout. By mid-2018, several countries with potentially large EV markets had set EV deployment targets, as well […]

An energy transition is underway across the world. Market upheaval, defining events, and recent policy changes have accelerated a shift away from coal toward renewables. Here is how this transformation played out for some of the world’s major economies over the past decade. Graphs show percent of each fuel source of total generation for that […]

Comments on the Department of Energy’s (DOE’s) proposed grid resiliency rule from an assortment of state agencies, trade groups, environmental organizations, and organized market entities flooded the Federal Energy Regulatory Commission’s (FERC’s) docket before the tight three-week timeframe expired Oct. 23. The DOE’s “Grid Resiliency Pricing Rule” proposed on Sept. 29 directs FERC—an independent regulatory […]
