Even assuming each of these objections are true (I’m not getting into squabbling about it), it’s rather noticable that you don’t present any meaningful alternatives.
There is a difference between proposing changes, and failing to view all sides of a proposed change.
In Oregon (as elsewhere) we have dammed rivers. There were benefits and costs to doing so.The benefits were low cost electrical power. The costs were largely unknown, but have resulted in a tremendous depletion of both salmon and steelhead fisheries. There has been a strong demand to remove dams (and some have been removed), but a difficult (to put it politely) part of the conversation is, how is the electrical generation replaced?
Coal? That is the current whipping boy.
Gas? That is rejected by many as creating CO2.
Nuclear? Need I even mention the opposition to this?
Solar? Inefficient in itself, and inefficient in our climate (lots of clouds, lots of rain).
Wind? There is a reason it is government subsidized, as the cost on its own is a non-starter.
Wave? That one seems to have come and gone, as little is heard about it, and there doesn’t seem to be any progress.
Geothermal? Works in some areas, not in others; again, little heard about this alternative.
Conservation is an excellent goal; but the difficulty is in having a conversation about the costs.
Lynnvinc talks about how “they have already figured wind is cost-competitive with conventional energy.” Not identified is who is saying that ti is cost competitive, and on what basis? Governments (as in European and the US) have used estimates of a 20 to 25 year lifespan for Wind Turbines. In 2012, studies showed that the lifespan was closer to 10 to 15 years. Additionally, a turbine generates more than twice as much electricity in its first year than it does in its 15th. The efficiency rating is reduced from 24% in the first year to just 11% after 15 years. And for offshore wind farms (Danish) the drop was even lower - from 39% in first year to 15% after only 10 years.
It might be cost competitive its first year; but as it starts dropping off, it becomes less so. Further, against what form of generation is it being compared? And where is the replacement figure, given that they need to be replaced far sooner than original estimates?
I am not against wind generation. We have it in eastern Oregon. What I am against is hiding the facts, and not addressing overall costs, including maintenance (it goes up generally as the turbine ages; and frequency is another issue - estimates vs. actual); additionally, large wind farms are creating more turbulence than originally estimated, which adds to the the maintenance costs.
It is not a matter of providing alternatives, as we have alternatives to coal, gas and oil. However, there is a basic underlying dishonesty about both the real world costs and the real world effectiveness of alternatives. That makes for nigh impossible conversations, as people with limited information ( I won’t call it false, but it is most definitely misleading) have bought in so emotionally that it will take failure of some of these systems to bring about a rational discussion.
Coal mining in the US has been dropping since 2008, due to the reduction in cost of natural gas, and to a lesser extent, to alternative forms of energy; although world wide the use of coal has increased, and is expected to continue to increase at about 2% per year until 2020. /the difficult part is that coal fired plants from asia to Africa are using decades old technology, which will result in more pollution.
And while costs of wind turbines has dropped 20 to 40 percent, that still does not leave a turbine paying for itself within its real-world life expectancy. And therein are the real but hidden costs against claims that it is cost effective.
Are there new technologies? Perhaps; there has been a good deal of research in nuclear energy as a means of prviding electricity; but that too is a conversation fraught with strong emotions - not too many people are signing up for what they consider to be the next Chernobyl or Fukushima, even if it can be considered far safer than the problem plants.
And efficiency in electrical demand in what we use (as well as areas such as autos) will most likely continue.
