Geographical wind smoothing, supergrids and energy storage
RENEWABLE ENERGY – CANNOT SUSTAIN AN ENERGY-INTENSIVE SOCIETY.
Be sure to read the linked papers. In the Arizona desert, solar has dropouts in mid day for no apparent reason.
Wind: There are rare places where wind works locally, but to power, for example, all of Europe, all of Europe and all of Asia has to be linked into one very expensive grid. You need the nameplate power times 4 spread over 12 time zones to get reliable power. The line losses are huge unless you have a superconducting grid, and superconductors now available require liquid nitrogen cooling.
The Germans are paying ~$ per kilowatt hour for renewable energy, assuming that nuclear + coal costs the same as what I am paying.
Sustainability . Sustainability is a notion that proposes that socially responsible firms will somehow financially outperform other less responsible firms in the long run. This might result from customer loyalty, better employee morale, or public policy favoring ethical conduct. Empirical results testing this hypothesis are mixed, neither suggesting that more responsible firms, on the average, have a clear financial advantage nor a large burden. Thus, a useful approach may be to determine (1) specific circumstances under which a firm may actually find the more responsible approach to be more profitable, (2) under which circumstances responsible behavior can be pursued without an overall significant downside, and (3) the ethical responsibilities that a firm faces when a more responsible approach may be more costly.
