Answer 1

What was found was that a 50-per-cent reduction in greenhouse-gas emissions could be achieved over the next 30 years with technologies that are already available. Here's some of what we can do:

The fuel efficiency of cars and trucks increases by a factor of two or three over current levels; the vehicles that can achieve this are already coming on the market. Gasoline/electric hybrid vehicles, along with appropriately fuelled hydrogen fuel cells and ethanol made from agricultural wastes all contribute to a drop of more than 60 per cent in emissions from transportation, even while total travel continues to increase.

The central power plant, truly a dinosaur of the 20th century, is replaced by the kind of small-scale, combined heat and power plant from which Denmark already gets most of its electricity, at two- to three-times the efficiency of power stations.

A comprehensive, nation-wide program retrofits 80 per cent of the nation's housing stock with measures such as increased insulation, new and energy-efficient windows, and compact fluorescent lights. More than a million person-years of skilled employment are required by the program. Meanwhile, new homes are built to the government's own R-2000 standard and solar energy begins to supply some domestic hot water.

Commercial buildings make similar gains, with new buildings replicating the demonstrated success of recent retail and office building green projects in which the buildings' energy requirements have been cut in half with no significant increases in construction cost.

It is simply not credible to argue that we can't reduce greenhouse-gas emissions by 50 per cent or more, and to do it in a relatively short time -- by the year 2030. These measures will result in less fossil-fuel use, but also a fossil-fuel industry that makes a transition to adding much higher-value products and services. In the bargain, we get reduced air pollution, improved public health, enormous wealth generation and job creation, and even enhanced national security.

There still remains the question of whether this could be done economically, to which the first response must be -- compared with what? Coping with climate change? Faced with a choice between investing in an efficient and sustainable energy system versus paying ever-increasing costs from floods, droughts, storms, air pollution, infrastructure damage, primary productivity loss, and environmental refugees.

Where will the smart money go?
