In the 20th century, global energy and water use grew significantly. Population growth and rising affluence will continue to drive demand for both resources. Different energy technologies have varying water needs, with thermal power plants having unique cooling system requirements.
Fuels like wood, diesel, and natural gas have shaped human energy history, driven by technological, economic, and environmental forces. Liquid fuels from oil, with their high mass and volumetric energy density, led to their supremacy in transportation. Shifts in fuel types also influence the devices that convert them into energy services.
In 1898, H. Riall Sankey developed a diagram illustrating steam engine efficiency, leading to the widespread use of Sankey diagrams for visualizing energy flows in various systems. They effectively display energy extraction, transformation, consumption, and losses while mapping the roles of primary and secondary energy sources across different usage sectors.
In 2023, US drivers consumed 376 million gallons of gasoline daily, with superusers accounting for 35% of usage. Rural areas have more superusers, spending 10.2% of their income on gasoline. They also tend to drive larger, less fuel-efficient vehicles. Electric vehicle policies targeting superusers could reduce energy burdens and emissions, benefiting low-income households.
The shift from fossil fuel-powered internal combustion engine vehicles to electric vehicles is a key strategy for reducing transportation emissions. Various regulations and incentives at the state and national level drive this transition, with California leading in policies and EV registrations. The growth of EV sales is supported by policy, lower prices, improved range, and expanded charging infrastructure.
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.
