Gore Says We Need Electricity without Fossil Fuels within 10 Years

In one short speech Al Gore compressed the time frame for generating all electricity without the use of fossil fuels from perhaps 40 years to only 10 years. He believes that 10 years is the maximum for the country to set a goal and that a massive effort should be undertaken to increase the use of renewable energy such as solar, wind, and geothermal. Considering that only a tiny fraction of our electricity now comes from solar, wind, and geothermal his challenge appears to be a tall order to say the least. According to The New York Times Gore said that the “goal is achievable, affordable and transformative.” Everyone would probably agree that it is transformative. Far fewer would agree that it is achievable and affordable. As do many people, Gore seems to emphasize the wonders of technological innovation as a key element in solving the global warming problem as well as the energy dependence problem. However, it appears that existing technology can take us pretty far.


Realistically, it seems that the only way fossil fuels can be phased out as a source of electricity in the near future is for the demand for electricity to sharply decrease. Initiatives such as The 30% Solution and The 2030 Challenge are aimed at doing just that as well a reducing the use of fossil fuels (oil and natural gas) for heating buildings. These initiatives are based on the use of stricter building energy codes. More efficient building can be built without the need to develop new technologies. Extremely energy efficient buildings are already being built. What we need is all new buildings to be built in this manner. Many buildings are also being renovated to make them far more energy efficient. Again, what we need is all new significant renovations to be done in this way.


Gore’s call for a phase out of fossil fuels for electricity within 10 years will probably just cause more apathy because it seems impossible and probably is. The trick is to call for changes that really are achievable but are still drastic enough to reduce greenhouse gas emissions enough to solve the climate crisis. It appears that Gore has yet to find the right formula.

The Nano Dilemma in the Fight Against Global Warming

In an op-ed piece in The Washington Post, Anne Applebaum points out a disturbing issue raised by the marketing of the Tata Nano, the $2,500 car that has just been introduced in India. She states that:

There must be a way to reconcile mass car ownership with global warming, but, at the moment, we haven't found it. There is no profound reason that good environmental policies have to come into conflict with economic growth, but they often do. In many countries, the desire not to be poor is stronger than the desire to breathe clean air.

It is hard to ignore that the fight against global warming seems to be on a collision course with efforts to provide masses of poor people in developing countries with better lives. Or as Applebaum states it:

What happens when the laudable, currently fashionable movement to improve the environment comes directly into conflict with the equally laudable, equally fashionable movement to improve the lives of the poor?

Right now there do not seem to be any good answers. China is said to building the equivalent of one coal-burning power plant a week. That certainly will improve the lives of tens of millions who lack electricity but pretty much negates efforts around the world to reduce carbon emissions. India seems to following the same course but at a slower rate. The situation appears even more hopeless when you consider the situation in the United States where everyone has electricity but about 150 coal-burning power plants are in the planning stage to meet projected increased electricity demand presumably because of such reasons that people are no longer satisfied with watching a 30-inch cathode ray tube television but want an energy gobbling 60-inch plasma screen instead. In the US more energy is needed to lift tens of millions of people out of a materially great life to an even more fantastic life. The world leaders who will be working the next two years to create an agreement to limit global warming may need something close to a miracle to succeed.
