The Fast Track To 100% Clean

We don’t need ‘miracle’ technologies to fix the climate. We have the tools now; Wind, water and solar energy is cheap, effective and green. We don’t need experimental or risky energy sources to save our planet

Mark Z Jacobson, February 7, 2023 (UK Guardian)

“…[Given the magnitude of the climate crisis,] it is no surprise that the best solution is one that can be implemented quickly and at low cost. Enter wind, water and solar (WWS). WWS includes energy from the wind (onshore and offshore wind electricity), the water (hydroelectricity, tidal and ocean current electricity, wave electricity, geothermal electricity and geothermal heat), and the sun (solar photovoltaic electricity, concentrated solar power electricity and heat, and direct solar heat)…When combined with electricity storage, heat storage, cold storage and hydrogen storage; techniques to encourage people to shift the time of their electricity use (demand response); a well-interconnected electrical transmission system…[and electrical appliances, WWS has a] low cost worldwide…

…[T]he energy that people use goes down by over 56% with a WWS system…[because of the efficiencies of electric vehicles, electric heat pumps for air and water heating, and] electrified industry…[A WWS system also] reduces the cost per unit energy by another 12% on average, resulting in a 63% lower annual energy cost worldwide…[With health and climate cost savings, there is] an overall 92% reduction in annual social cost (which is the energy plus health plus climate cost) relative to a conventional system…

The worldwide upfront capital cost of such a 2050 WWS system is around $62tn. However, due to the $11tn annual energy cost savings, the payback time is less than six years. The new system may also create over 28m more long-term, full-time jobs than lost worldwide, and may require only about 0.53% of the world’s land for new energy – less than the land required for the current energy system…[We] have 95% of the technologies we need to solve the problem…We do not need carbon capture and storage or use, direct air capture storage or use, blue hydrogen, new nuclear power, or bioenergy…” click here for more
