The Promise of Fusion Energy
Fusion energy represents a potential revolution in how we generate power, moving away from fossil fuels towards a cleaner, more abundant energy source. This process involves fusing light elements like deuterium and tritium to produce energy, akin to the reaction that powers the sun. The energy produced from fusion can yield significant amounts, with just one fusion reaction equating to the energy in 5,000 barrels of oil. Importantly, the fuel for fusion is plentiful, with deuterium available in seawater and tritium producible from lithium, allowing for energy security that could last for billions of years.
