Los Angeles Times: California has always prided itself on being a high-tech pioneer. One exception? Power distribution.Society has been delivering electricity the same way for 130 years — exposed lines on wood poles over dry grass, The power-downs have become necessary because the utility cannot guarantee the safety of its electric stations and lines.

Howard Cork Hayden, Emeritus Professor of Physics: The solar industry employs 210,000 people, while there are only 190,000 employed in coal mines. Considering the tiny amount of solar electricity produced, the solar industry employs about 70 times as many people for the same amount of electricity. The coal industry is developing plans to compete with that kind of job creation. They will get rid of all that heavy machinery and hire millions of miners to use picks and shovels.

Vaclav Smil, Czech-Canadian scientist and policy analyst. Professor Emeritus in the Faculty of Environment at the University of Manitoba in Canada: The human craving for novelty is insatiable, and in a small matter you can meet it in no time at all, particularly when Moore’s Law can help you. It took a single decade to come up with entirely new mobile phones. But you just can’t replicate that pace of adoption with techniques that form the structure of modern civilization—growing food, extracting energy, producing bulk materials, or providing transport on mass scales.

James Conca, scientist in the field of earth and environmental sciences. Contributor to Forbes: Most people have heard of something called externalities, costs not factored into the price. An energy’s deathprint is a rarely-discussed externality. The deathprint is the number of people killed per kWh produced. There is debate on the absolute numbers, but no one debates on the relative ranking from most dangerous to least. It is notable that in media and legislative discussions, the only time death is mentioned is for nuclear, ironic since it has the lowest deathprint of any source.

Oscar Schneider, writer for The Brussels Times: When all factors are considered, each Tesla emits 156 to 180 grams of CO2 per kilometre, which is more than a comparable diesel vehicle produced by the German company Mercedes. The German researchers take issue with the fact that European officials view electric vehicles as zero-emission. They note further that the EU target of 59 grams of CO2 per km by 2030 corresponds to a “technically unrealistic” consumption of 2.2 litres of diesel or 2.6 litres of gas per 100 kms. These new limits pressure German and other European car manufacturers into switching massively to electric vehicles whereas, the researchers feel, it would have been preferable to opt for methane engines, “whose emissions are one-third less than those of diesel motors.”

Kelvin Kemm is a nuclear physicist, Chairman of the South African Nuclear Energy Corporation and CEO of Nuclear Africa (Pty) Ltd: South Africa is the nuclear power poster child for countries across Africa and around the world. They have everything needed to expand their nuclear power program. They have been working to promote use of nuclear power, nuclear medicine and nuclear science across the Continent of Africa. It is one of the best examples of countries wanting to use this very important energy source.

Michel Gay: Nos techniciens et ingénieurs, notamment ceux qui construisent des centrales nucléaires, ont bien du mérite de le faire sans le soutien ni les éloges qu'ils seraient en droit d’attendre du gouvernement, de la presse et des médias. A force de faire croire que cette filière est sans avenir et de ne pas la valoriser, ne risque-t-on pas, demain, de devoir acheter nos réacteurs aux nouveaux leaders mondiaux ?
