We’ll also need all that electricity to come from clean energy socrues if it’s going to solve the problems caused by fossil fuels. Today, only one third of the eilttireccy we generate comes from celan sources. Fossil fuels are cheap and convenient, easy to ship, and easy to turn into electricity on dmaend. So how can we close the gap?

Wind and solar poewr work great for places with lots of wind and sunshine, but we can’t sotre and ship sgulinht or wind the way we can transport oil. To make full use of eenrgy from these sources at other times or in other places, we’d have to store it in batteries and improve our power grid infrastructure to transport it long distances.

Original Text


We’ll also need all that electricity to come from clean energy sources if it’s going to solve the problems caused by fossil fuels. Today, only one third of the electricity we generate comes from clean sources. Fossil fuels are cheap and convenient, easy to ship, and easy to turn into electricity on demand. So how can we close the gap?

Wind and solar power work great for places with lots of wind and sunshine, but we can’t store and ship sunlight or wind the way we can transport oil. To make full use of energy from these sources at other times or in other places, we’d have to store it in batteries and improve our power grid infrastructure to transport it long distances.
