How Today’s Technology Can Save Our Climate and Clean Our Air: Mark Z. Jacobson

We’re excited to welcome back Mark Z. Jacobson, who joined us last year to talk about a study he co-authored called “Low-Cost Solutions to Global Warming, Air Pollution, and Energy Insecurity for 145 Countries”. He is a professor of Civil and Environmental Engineering and Director of the Atmosphere/Energy program at Stanford University, as well as a Senior Fellow at the Woods Institute for the Environment and Precourt Institute for energy, and also the Co-Founder of The Solutions Project, 100.org and the 100% Clean, Renewable Energy movement.

We've asked Mark back to see what progress the country has made with his prediction that the US and the world can change to clean energy and meet CO2 goals by only using WWS (wind, water and solar) i.e. clean non burning energy without using coal, gas, nuclear, and carbon capture. Mark released a book in February of this year, entitled No Miracles Needed: How Today’s Technology Can Save Our Climate and Clean Our Air. His book brings up more questions about the government and the some climate experts are promoting, such as carbon capture, instead of considering the potential of just using WWS. 

Topics covered include:

• How does the time taken to construct different types of power plants effect their impact  in light of the short timetable on lowering CO2 and other greenhouse gases pollution?
• How does the amount of waste heat  released by fossil fuel compare to that released by renewables? For example,  about 65 to 67 percent of energy in oil and coal is released as waste heat, 40 to 60 percent of natural gas energy is also waste heat, 74 percent of biomass is waste heat and 65 percent of the energy in uranium is waste heat.
• According to Jacobson, “By 2021, the cost of a system consisting of wind, solar, and batteries was already less than that consisting of natural gas. For example, even in 2019, a Florida utility replaced two natural gas plants with a combined solar-battery system because of the lower cost of the later.” How do economics affect transition to renewable energy sources? 
• What are the best and quickest energy source for commercial and military planes and cargo ships?
• Is the U.S. grid ready for 100 percent clean electricity?
• What has been the reaction to Jacobson's proposed  WWS solution?
