Energy Sources
From fossil fuels to fusion - explore every major energy type that powers our world. How they work, their trade-offs, and where they're headed.
Nuclear Energy
Splitting atoms for immense power
Energy released from nuclear fission or fusion reactions. One of the most energy-dense sources known to science.
Solar Energy
Harvesting the power of the sun
Energy captured from sunlight using photovoltaic cells or concentrated solar power systems.
Wind Energy
Turning air movement into electricity
Kinetic energy from wind captured by turbine blades to drive generators and produce electricity.
Hydropower
Gravity-driven water power
The largest source of renewable electricity, harnessing the energy of falling or flowing water.
Natural Gas
The "bridge" fossil fuel
Methane-rich fossil fuel used in power plants, heating, and industry. Cleaner than coal but still a significant emitter.
Coal
The original industrial fuel
The world's most used fossil fuel for electricity, responsible for the largest share of energy-related COโ emissions.
Geothermal Energy
Earth's internal heat, unlocked
Energy extracted from Earth's internal heat via steam or hot water reservoirs, used for electricity and direct heating.
Biomass & Bioenergy
Ancient solar energy, recycled
Energy from organic materials - wood, crops, waste. Controversial due to land use and emissions debates.
Hydrogen Energy
The versatile energy carrier
Hydrogen as an energy carrier produced from various sources, used in fuel cells, industry, and potentially aviation and shipping.
Tidal & Wave Energy
Harnessing the ocean's rhythm
Marine energy from tidal currents, tidal range, and ocean waves - highly predictable and abundant but still early-stage.
Oil & Petroleum
The lifeblood of the modern economy
Liquid fossil fuel dominating transport, petrochemicals, and heating. The largest single energy source globally.
Nuclear Fusion
The power of stars - almost here
The ultimate clean energy source - fusing light atoms releases tremendous energy with no long-lived waste. Still in development.
