Hydropower’s history traces back to 1882 when the first facility began supplying electricity in Wisconsin. Its adoption surged across North America, Europe, and beyond, with China notably driving expansion in recent decades. Hydropower now contributes 17% of global electricity, surpassing nuclear, wind, solar, bioenergy, and geothermal combined.
Biopower is electricity generated from renewable organic materials, such as plants and animals. Different countries rely on various biomass sources, including sugarcane, trees, and municipal waste, to produce biopower. However, the impact of biopower on climate change is complex. Despite being initially perceived as carbon neutral, the use of fossil fuels in bioenergy systems and the land requirements for biomass production can have significant environmental consequences.
The use of biomass by humans can be traced back at least 1 million years to the controlled use of fire. However, the generation of electricity from biomass, known as biopower, is a more recent development. One of the earliest biopower plants was the São José da Estiva power station in Brazil, which began operating in 1900.
Of the millions of wells drilled, approximately 3.5 million are now abandoned, with some being properly plugged and others left unplugged. Unplugged wells can emit greenhouse gases, contaminate surrounding environments, and pose safety hazards. Orphaned wells, which lack a responsible operator, become the financial responsibility of the government and taxpayers.
Global natural gas consumption has risen 70% from 2000 to 2022, fueled by economic growth and coal-to-gas transition. Hydraulic fracturing in the US has played a major role. Liquefied natural gas (LNG) enables long-distance shipping, but presents climate and energy justice challenges.
In 2020, 437 new solar electricity projects worldwide added a total capacity of 38,941 MW. The largest project was the 1348 MW Karapınar YEKA-1 solar farm in Turkey. Asia, North America, and Europe were the main contributors to solar capacity, with China leading with 23% of the global additions.
Explore the global history of nuclear reactors from 1951 to 2022. This visualization showcases 626 operational reactors, highlighting the dominance of pressurized light water reactors (PWRs). Different reactor types exhibit geographic patterns, with retired reactors and ongoing upgrades observed in various countries. The average age of reactors in the United States was 41 years in 2021.
Texas has emerged as a prominent oil and gas producer, ranking as the fifth largest oil producer globally if it were its own country. The development of fracking technology and a surge in oil prices led to a significant increase in oil and gas production in Texas from 2000 to 2014. However, the distribution of employment gains during this boom varied across gender, race, and ethnicity. The Texas example underscores the importance of ensuring an equitable distribution of economic benefits in energy systems, especially as governments incentivize low carbon energy initiatives.
Uranium is crucial for nuclear power generation, supplying 10% of global electricity. The largest recoverable uranium resources are held by Australia, Kazakhstan, Canada, Russia, and Namibia. Major uranium consumers rely on imports due to limited domestic production, leading to significant international trade in uranium products.
The safety of nuclear reactors is a subject of debate. While incidents like Three Mile Island, Chernobyl, and Fukushima have had impacts on human health and the environment, the overall risks of radiation exposure are considered small. Advancements in technology and regulations have significantly reduced the frequency of core damage incidents. Nuclear power is an important low-carbon energy source, but opinions differ on its safety compared to fossil fuels and renewables.
