Capell Aris, Fellow of the Institute of Engineering and Technology: This paper assesses the cost effectiveness of installing a battery for storage of electricity generated by solar PV rooftop panels. Solar PV can reduce grid import by as much as 40% without need of battery storage. Consumers can shift electric demand to the solar peak production. The low level of winter solar generation in the UK means that battery storage will not be worthwhile.

Paul Driessen, Committee For A Constructive Tomorrow, CFACT: In a world where we are supposed to ban nuclear (and most hydroelectric) power, the very notion of eliminating the 80% of all global energy that comes from oil, natural gas and coal – replacing it with wind, solar and biofuel power – is fundamentally absurd. Now the focus is on climate change. Every EV sale will help prevent assumed and asserted man-made temperature, climate and weather disasters, we’re told – even if their total sales represented less than 1% of all U.S. car and light truck sales in 2016 (Tesla sold 47,184 of the 17,557,955 vehicles sold nationwide last year), and plug-in EVs account for barely 0.15% of 1.4 billion vehicles on the road worldwide.

Paul Driessen, CFACT: Hybrid and electric vehicles are not so “green” and “eco-friendly,” after all. Ditto for cell phones, laptops, wind turbines, solar panels, and technologies that utilize batteries, magnets and other components which require cobalt, lithium, rare-earths, and other metals. Many of those technologies trace their ancestry to mines, mining and processing methods, and countries that don’t come close to meeting modern standards for environmental protection, child labor, or “corporate social responsibility.
