🌍⚡️The transition from today's wasteful economy to a sustainable economy is described in Tesla's Master Plan 3. A must read. tesla.com/ns_videos/Tesla-Ma… A few interesting notes: - 64% of energy is currently wasted as heat (so if you have 100 power plants, only 36 of them power useful work!) - In the future, there will be less waste heat (only 10%) - In this study, it is assumed 22% more useful work & heat is needed in the future scenario, probably assuming rising demand - Without this additional demand (comparing apples-to-apples), the world would need to produce only 93PWh/y, compared to 165 today, which is 56% of today's production! - In the future, there will be significant renewables curtailment (26% of produced energy) Curtailing renewables means not using available power when it is not needed at a given time (say all batteries are already full and it's noon in the summer). This is necessary, due to building extra capacity to serve peak demand (which is already a practice with the current grid). @tonyseba calls this Super Power, because soon, industries will learn to use this extra energy, as it comes free. This will reduce the amount of curtailed energy over time. Even with the assumed 26% of curtailed energy, the sustainable economy is vastly cheaper than the current economy. Looking at the next 20 years, it will cost the world $14T to continue with fossil fuels, or $10T to fully transition to renewables. After this 20-year period, it will still cost trillions to run on fossil fuels, but it will cost almost nothing to run on renewables as the investment has been completed and the sun/wind is free. All that does not even take into account CO2 emissions, and the impact on health and climate change.
