Meredith Angwin, Physical Chemist, Naturalist, Educator, Robert Bryce, author of “Smaller Faster Lighter Denser Cheaper,” and many other books and articles about energy : The modern world depends on a few essential networks: telephone, GPS, and of course, the World Wide Web. And all of those networks rely on the mother network: the electric grid. In Shorting the Grid, Meredith Angwin provides an enormously valuable, clear, and succinct explanation of our most important network. She shows how it works, why it’s vulnerable, and why we should be concerned about what she lyrically calls the "angelic miracle of the power grid.”
Raphael Telis, research physicist at BNL and CERN: One of the most widespread myths is that wind and solar power sources are inexhaustible because the wind will always blow and the sun will always shine. This statement assumes that all that is needed for energy is wind and sunshine, which isn’t the case. Wind and sunshine don't equal wind power and solar power. The transformation into renewable energy requires minerals, metals and fossil fuels, which are non-renewable resources. Thus, wind turbines and solar panels are largely made from non-renewable resources. Take a note: "renewable energy" isn't a technical or scientific term but a marketing term.
Rob Jeffrey, Independent Economic Risk Consultant: It is claimed that wind and solar are the cheapest sources of electricity and these sources should dominate the future electricity supply. This paper focuses on known additional costs and subsidies which are not taken into account by their advocates. Advocates of wind and solar claim a cost of 62cents/kWh. This is, however, the price at the gate of the supplier. It does not include all the costs of supply necessary to convert this electricity from non-dispatchable electricity supply to dispatchable electricity supply at the point of supply to the customer. These are in effect direct subsidies to solar and wind suppliers, whereas they should be added as a cost to the renewable energy suppliers
Jay Lehr, Ph.D. Science Contributor, CFACT: Why is wind power and solar power, not making significant gains in providing a substantial amount of renewable electricity? The US has utilized, in its energy mix, about eight percent of wind and two percent solar for more than a decade. The reason it is not growing requires an understanding of the fundamental elements, of an electrical grid.
