Energy Cheat Sheet

Construction Physics • 85601 implied HN points • 20 Dec 24
🌞 Climate & Environment Energy Systems Infrastructure Decarbonization Renewable Energy Efficiency
  1. Energy is the ability to do work, like moving or changing things. Everything we do requires energy, and we can't create or destroy it, only change its form.
  2. Most of the energy we use gets wasted, with many losses occurring during energy transformations. Only about a third of the energy consumed goes towards useful work.
  3. Hydrocarbons, like oil and gas, are easy to store and transport, but as we shift to electricity, we need better storage solutions to manage fluctuations in supply and demand.
