 Why is everyone talking about net zero emissions? Well, humanity puts greenhouse gas emissions up into the atmosphere and we need to stop doing that to stop global warming. How are we going to do it? Well, we're going to largely stop the burning of coal, oil and gas. We're going to drastically reduce various greenhouse gas emissions from industry as well as from agriculture. That will get us most of the way to zero, but not all the way. And the remaining emissions we will compensate for by drawing carbon dioxide out of the atmosphere, putting it underground or using it as products. What's the key for it? Well, it's electricity supply. We need clean power, carbon-free electricity, which then can be used throughout the economy and displays the oil, gas and coal that we're currently using directly. That is the key to net zero, a clean power supply.
