Solar energy is a form of carbon-free, renewable energy, in which sunlight is turned into electricity, heat, or other forms of energy we can use.| MIT Climate Portal
Renewable energy is energy from sources, like wind, solar, and hydropower, that we cannot run out of.| MIT Climate Portal
Nuclear energy is low-carbon energy made by breaking the bonds that hold particles together inside an atom.| MIT Climate Portal
Mining provides us with the building blocks of modern society, but much of the energy used to get minerals out of the ground, and process them, today comes from fossil fuels.| MIT Climate Portal
Energy storage is technology that holds energy at one time so it can be used at another time. Cheap and abundant energy storage is a key challenge for a low-carbon energy system.| MIT Climate Portal
Greenhouse gases are gases—like carbon dioxide, methane, and nitrous oxide—that keep the Earth warmer than it would be without them.| MIT Climate Portal
