“Forever is composed of nows”

Emily Dickinson

Honda thinks my new Civic will be worth $12,000 three years from now. I don’t think so. Here’s why.

Gas is inevitably going up up up because of emerging, energy-hungry markets in Asia and the rest of the world.

Higher Demand+ Limited Supply= Higher Prices.

A car that gets ‘only’ 25/36 MPG won’t be in demand.

New car technology, including plug-in hybrids, will be the standard because the demand will be intense and the technology exists now.

As the Car Lady pointed out in a recent comment, leasing is definitely the way to go right now because of these factors. Things are changing so fast that you can’t risk owning an expensive piece of equipment that will become outdated before it is even paid for.

Welcome to the future.

Solar thermal power is generated by building a field of concave mirrors that focus the sun’s heat onto a liquid encased in pipes. The liquid is superheated and used to generate steam that powers turbines, generating electricity. In the south west, where open desert land and sunlight are plentiful, they are building these facilities as fast as they can. They are completely unrelated to conventional solar panels that convert light into electricity but are very costly to build.

“On sunny afternoons, those 10 plants would produce as much electricity as three nuclear reactors, but they can be built in as little as two years, compared with a decade or longer for a nuclear plant. Some of the new plants will feature systems that allow them to store heat and generate electricity for hours after sunset.”

New designs that focus the heat onto towers will work in less sunny areas. With a lot of discussion about starting to build new nuclear plants which are very efficient but create an unsustainable stream of radioactive waste, it’s important to understand that we have very clean alternatives. There are environmental impacts of building these large facilities on open land but they are nothing compared to the impact of any conventional energy source such as coal, gas or nuclear.

During a press conference last week Bush asked what he thought about economists’ predictions that we would see $4+ gas prices by early spring. He was surprised and said he had not heard that. This is frightening to say the least. The President of the United States, who started a war over oil that is estimated to cost us $5 trillion dollars before it is over, doesn’t know how much gas costs. I wonder if he knows what a burden this is for the average family- prices have tripled during his administration. And it’s not just gas. Heating oil and energy prices have skyrocketed.

Today oil passed the inflation-adjusted high reached during the Arab Oil Crisis of the late seventies and early eighties. World stock markets are in a tailspin. The House of Representatives have passed a bill ending $17 billion in handouts to oil companies (who made $146 billion in profits last year) and moving that money into alternative energy tax credits. These credits are critical to encouraging rapid development of sustainable energy alternatives that can help us end our oil addiction. Yet Republicans in the Senate are blocking this bill and the President is threatening a veto. This partisan block voting is destroying our economy in exchange for short term gain by an industry sector intimately associated with this Administration.

Apparently it’s not rocket science to do this but it would require a lot of power so they are proposing creating a nuclear-powered gasoline generation plant that would convert carbon dioxide into gas.

Just one more technology solution to throw into the mix. This one becomes viable when gas at the pump hits $4.60/gallon. The national average cost a year ago was $2.26, today its around $3.20 but oil closed above $100/barrel yesterday for the first time so that $4+ number could happen this year.

The economics of alternative energy sources get a lot more compelling as prices rise, just as do those of public transportation.
