Not far from the blinking casinos of this gambler's paradise lies what could be called the Biggest Little Power Plant in the World. Tucked into a few dusty acres across from a shopping mall, it uses steam heat from deep within the Earth's crust to generate electricity. Known as geothermal, the energy is clean, reliable and so abundant that this facility produces more than enough electricity to power every home in Reno, population 221,000. "There's no smoke.

What do Icelanders know about heat? Quite a lot, it turns out. For 70 years, the chilly island nation has been tapping the Earth's warmth -- using geothermal energy to heat buildings and swimming pools, melt snow and generate more than a quarter of the country's electricity. And now they've come to California to share the knowledge.

When tremors started cracking walls and bathroom tiles in this Swiss city on the Rhine, engineers knew they had a problem. "The glass vases on the shelf rattled, and there was a loud bang," Catherine Wueest, a teashop owner, recalls. "I thought a truck had crashed into the building." But the 3.4-magnitude tremor on the evening of Dec.

Hoping to tap into California's growing appetite for renewable power, Calpine Corp. today will unveil an ambitious expansion of its geothermal operations, considered one of the state's most promising clean-energy sources. The overhaul of the Geysers geothermal project, expected to cost $75 million in its first year, is evidence of the strong demand for cleaner energy in California.

Indonesia, land of earthquakes and volcanoes, may be sitting on top of the solution for its energy needs: vast reservoirs of hot water deep beneath the earth's crust that can be harnessed to generate electricity. What's more, it's a clean, renewable energy source. Yet the country imports millions of barrels of oil and fuel annually. Legal uncertainties, financial risks and government bureaucracy have repelled international investors from developing its geothermal resources.

Re "Mining the Imagination for New Energy," Opinion, July 25: Alan Weisman thoughtfully highlights one of the major concerns facing world civilization over the next century: our rapidly increasing world population with its concomitant, exponentially increasing use of energy, coupled with a greatly diminished availability of oil, the lifeblood of our civilization. Weisman mentions a variety of imaginative "long shot" possible solutions, none of which appear very practical, but does not consider the obvious one -- to decrease the world population to the point where it will be in equilibrium with renewable energy sources: solar energy, wind, biomass, geothermal energy and hydroelectric.
