Cost of Energy ...
The cost of energy continues on a long-term upward climb with some variation due to short-term economic influences. This is to be expected. The rest of the world is using more energy per capita as it becomes more industrialized. And, the population continues to rise. The supply of energy has not kept pace with demand and barring some quantum technological breakthrough it doesn't look like it will. So, even in a a truly free market, basic supply and demand theory says we will have increasing prices for energy.
But
it isn't a free market. Nowhere near. It is dominated by one primary
commodity (oil), and that commodity is subject to global cartel actions
(OPEC). Then, the refinement of crude oil into usable products and the
distribution of those products is subject to localized monopolies.
Nope, not a free market. It's open to all kinds of shinanigans on
the parts of the nations and companies that control it.
'Global Warming' ...
It
appears that global temperatures are rising. This is not unexpected. We
are recovering from a major ice age somewhere ten thousand years ago,
and a minor ice age just a few hundred years ago. These are natural
events, occuring regularly long before human ability to influence them.
The recent temperature increases may be partially due to human
activity, specifically the release of significant amounts of previously
sequestered carbon compounds, burned to create carbon dioxide.
Just how much of the recent (in geological timescales) increases
in temperature are due to human involvement is a subject of significant
debate. That is useless debate. Let me repeat. Useless.
The important points of debate are:
- To what extent can mankind reverse the trend, and how? and,
- What is the cost/benefit of doing so?
- Are there better ways of deploying resources?
- If mankind is not the dominant cause, it's a good bet that reducing CO2 output will not significantly reduce temperature increases
- If mankind's CO2 output is the dominant cause, is it technologically possible to find alternative sources of energy that can make a difference?
To the third point: Given that temperatures are rising and we have finite resources to deal with the matter, how are those resources best used? We might well come to a consensus that mankind is a primary contributor to global warming, and that there are expensive courses of action that might reduce global warming. What to then? Are the resources that might be availabale to avert or delay global warming better spent doing that or preparing a world to deal with it? For example, living in a city that is below sea level, on a coast that is frequented by severe hurricanes is probably not wise. Especially if sea levels are expected to rises and storms may become more frequent and violent. Are limited resources better spent battling CO2 levels or encouraging movement away from problem areas? It's a discussion that needs to be had at the global level.
What's the solution?
In the short term, we need the energy we can get. I advocate the production of oil from the North Slope of Alaska and from other off-shore areas.
In the medium term, we need an abundant source of energy that is realizable at reasonable cost with acceptable levels of environmental risk. There aren't a lot of those right now. The best bet is nuclear. The technology has advanced over the past several decades to where risks of catastrophic releases of radiation are very small. Disposal is the last hurdle. We need to get disposal and reprocessing facilities up and running. When that's done, nuclear can be a clean source of energy for decades or centuries to come.
In the long term I don't know what the solutions are. They are probably not those technologies that are widely ballyhoo'd, like solar and wind. They aren't economically viable now, and for a number of technical reasons it is not likely that they will provide serious solutions in the long term.
