Coal has played a pivotal role in the United States’ industrial history, fueling steel production, electricity generation, and economic growth in the early 20th century. However, this legacy also comes with significant environmental and health issues, including miner health problems, landscape degradation, abandoned mines, and pollution.
The United States has played a significant role in global oil production, contributing 17% since 1900, with Texas being a major player, accounting for one-third of the nation’s oil production. Technological advancements like hydraulic fracturing and horizontal drilling led to record U.S. oil production in the 2010s, making the country the world’s largest oil producer and a net oil exporter.
Since the first successful oil well in 1859, the U.S. has drilled millions of wells for oil and gas. Drilling surged with demand, technology, and geopolitics, with notable periods like the post-WWII boom and the fracking-driven increase in natural gas wells. This progress has brought economic benefits and energy shifts, yet also raised environmental and social concerns.
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.
The fuel efficiency of personal highway vehicles, particularly gasoline-powered cars and trucks in the United States, is a crucial factor in energy consumption. Vehicle weight significantly affects fuel efficiency due to basic physics principles like inertia and rolling resistance.
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.
Climate justice recognizes the responsibility of the wealthy for climate change, which disproportionately impacts the vulnerable. Urban climate action plans are increasingly addressing justice, but some cities still lack such plans. Larger cities tend to prioritize justice more, and sectors like energy efficiency and clean energy receive greater attention. More efforts are needed to achieve just and inclusive urban climate transitions.
From 1900 to 2022, global electricity generation grew remarkably from 66.4 TWh to 29,165 TWh. Fossil fuels maintained a stable share of around 60% throughout this period, while renewables like wind and solar saw rapid growth from the 2000s. The 1960s saw a rise in oil power plants, but energy price shocks in the 1970s shifted focus to natural gas and nuclear generation, with significant investments in gas power plants from the 2000s onward.
The efficiency of a thermal power plant is the ratio of the electricity output to the energy input, taking into account the heat losses. Over the years, the average efficiency of thermal power plants using fossil fuels in the United States has significantly increased, from 4% in 1900 to 43% in 2023. This improvement is attributed to reducing heat loss in the three main energy conversion processes: fuel combustion, steam generation, and electricity generation.
