Thanks for posting this Perry and thank you Yogi for a great summary of the current situation and the outlook for the future. Sorry that I wasn't able to attend live. There are a few things that I think were missed in the presentation. There are several technologies that are coming online that will make energy storage more efficient, which will have a big impact on the capacity of the grid. Electric vehicles will require extra infrastructure, but their batteries can be used to supply peaking power to a smart grid. Gravity batteries, hydro pumping, CO2 gas batteries, sand batteries and more all have a part to play. I expect that fossil fuels will continue to rise in consumption until we can find alternate sources of energy. I expect that we will see a significant rise in safe modular micro-nuclear and traditional nuclear power. Distributed power production will play a part too, so communities developing their own energy using combinations of solar/wind/geothermal/micro-nuclear, etc., will have an impact on emissions. Generating power in remote locations and storing it in the form of hydrogen/ammonia will be a big deal in the near future, and the technology that I'm working to develop - Polar Energy Platforms will have a part to play in that. Within the last two years, at a Tesla presentation the company presented a plan to reach net zero by transitioning to electric vehicles, and expanding the network of solar energy. You alluded to more efficient windows. I'm working with a company to increase the thermal resistance of windows by more than a factor of 10, and it will work for walls too, making them more efficient than the current building code standards require and passively saving energy. I also think that just as developing nations skipped the whole phase of having a telephone system that was wired to the network and adopted cell phone technology instead, they will be able to benefit from the developments in solar and other renewable technologies and go straight to smart, self-driving, shared electric vehicles and skip the whole gasoline/diesel individually owned vehicle. I think that economics will move us toward renewable energy. It's already less expensive to use solar energy with a battery system than it is to buy electricity from the grid with all of the associated connection fees.
