- 19:57, 26 March 2024 Elie talk contribs uploaded a new version of File:energy-demand-pie1.png (Removed the lightning bolt, made it more clear that "watts" includes more than just electricity)
- 19:14, 26 March 2024 Elie talk contribs created page Wasted electricity is the same as electric heating (Created page with "A watt is a watt, when it comes to heating. All indoor electricity usage will heat the home the same way. Note: * If your local electricity is generated by coal or natural gas, then electric heating is 2-3 times worse (climate change) than a gas-burning furnace. Most power plants are only 33% efficient. * Wasted electricity is equivalent to a space heater. It won't heat as efficiently as a heat pump. ==See also== * Reduce energy demand")

We love short small pages of original research that are tightly linked to each other. * Say things in the simplest way possible, but not simpler. When in doubt, make separate pages for the details. * We love math and original research. We don't care if it's formal, but it needs to be honest.")

It's simple: Greenland and Antarctica aren't floating in water. There is land underneath. When their massive ice sheets melt, it flows into the ocean, raising the water levels.")
