For the overwhelming majority of human history, the only sources of mechanical energy available were the muscles of human beings and the animals they domesticated and put to work. Every civilization that built temples, plowed fields, moved armies, constructed roads, and…

Throughout human history, the primary source of energy for transportation has been biological: the metabolic energy of horses, oxen, camels, and other animals converted grass and grain into the motion that moved people and goods. The twentieth century's replacement of animal…

Coal is a combustible black or brownish-black sedimentary rock formed from the remains of ancient plants compressed and transformed over millions of years by heat, pressure, and geological processes. It is the most abundant fossil fuel on Earth, the largest single source of…
Energy is most useful when it can be available on demand — when the lights come on at the flip of a switch, when the engine starts at the turn of a key, when the furnace fires at the touch of a thermostat. Yet energy generation rarely coincides perfectly with energy demand: the…

Geothermal energy — the heat stored within the earth — is one of the most ancient energy sources used by humanity and one of the most reliable forms of renewable energy available. Unlike solar and wind power, which vary with weather and time of day, geothermal energy is…
Hydrogen is the most abundant element in the universe, constituting approximately seventy-five percent of all baryonic matter by mass and found in vast quantities in stars, gas clouds, and the primordial composition of the cosmos. On earth, however, hydrogen rarely exists in its…

Hydropower — the conversion of the kinetic and potential energy of flowing and falling water into mechanical work and electricity — is the oldest continuously used source of mechanical energy in human civilization and the world's largest source of renewable electricity today…
Natural gas is a fossil fuel composed primarily of methane (typically eighty to ninety-five percent), with smaller proportions of ethane, propane, butane, and other hydrocarbons, as well as non-hydrocarbon gases including nitrogen, carbon dioxide, and sometimes hydrogen sulfide…

Nuclear energy — the release of energy stored in the nuclei of atoms through fission (the splitting of heavy atoms) or, in the future, fusion (the joining of light atoms) — is among the most powerful and consequential technologies ever developed by human civilization. In a…
Petroleum — from the Latin petra (rock) and oleum (oil), the rock oil that seeps to the surface in hundreds of locations around the world — is the most economically and geopolitically consequential energy resource in human history. In fewer than 170 years since the first…
Beneath vast stretches of the Canadian and American west, beneath the mountains of Estonia and Scotland, and under the deserts of Brazil and China lie enormous deposits of hydrocarbon-bearing rock and sand that have transformed the global energy landscape since their large-scale…
Peat is a dark, spongy material formed by the partial decomposition of plant matter — primarily mosses, sedges, reeds, and other wetland vegetation — in waterlogged, oxygen-poor conditions. In the cold, wet boglands of northern Europe, northern Canada, Russia, and other…
Solar energy — the radiant light and heat from the sun — is the most abundant energy source available to humanity and the ultimate origin of nearly all other energy forms on earth. Fossil fuels are the fossilized remains of ancient organisms whose energy came from the sun; wind…
The world's oceans cover approximately seventy-one percent of the earth's surface and contain an enormous store of kinetic and potential energy in the form of tides, waves, currents, and thermal gradients. This ocean energy — driven by the gravitational pull of the moon and sun…
Every day, humanity generates approximately two billion tonnes of municipal solid waste per year — the discarded packaging, food scraps, obsolete goods, and byproducts of modern consumption. Managing this waste stream is one of the major challenges of urban civilization…
Wind energy — the harnessing of the kinetic energy in moving air — is among the oldest forms of mechanical power used by human civilization and one of the fastest-growing energy technologies of the twenty-first century. Wind has propelled ships across oceans since at least 3400…
Long before coal, oil, or natural gas, before nuclear reactors and solar panels, before windmills and waterwheels, humanity burned wood. Fire and wood — inseparable for nearly all of human history — represent the foundation upon which every subsequent energy technology was…
Wood, fire, and biomass energy represent the oldest and most enduring relationship between human civilization and the natural world. Before the wheel, before agriculture, before the first city rose from the alluvial plains of Mesopotamia, human beings had mastered the controlled…
