With oil futures soaring above $ 55 a barrel and natural gas doubling in
price in the last two years, renewable energy is looking a lot better to many --
not just on environmental merits but on price. Dollars in the wind Experts estimate that, at today's consumption rates, known global supplies of
oil and natural gas would be depleted within decades. But prices are expected to
rise significantly long before supplies run out, making those fuels too
expensive to use at current levels. In the short term, fossil fuel prices are being driven up by war, political
instability, natural disasters and other variables. The long-term outlook is
clearer -- global supplies are dwindling as demand soars, particularly in China
and India, where automobiles are multiplying and economies are growing at
breakneck speed. Meanwhile, improving technology, tax credits, low interest rates and
government mandates are making renewables more widely available, establishing an
inexhaustible energy supply that will keep driving prices down. Sixteen states,
including California, New York and Texas, have adopted "renewable portfolio
standards" that require utilities to buy a certain share of their
electricity from renewable sources. Less than 3 % of US electricity now comes from renewables such as wind,
solar, geothermal, wood and waste, but that share is expected to increase as the
price of fossil fuel rises. Help is needed The Energy Information Administration has calculated the average price --
factoring in fuel, construction and operating costs -- of various electricity
sources over 20 years starting in 2010. It estimates that wind would cost $
50.54 per MWh, compared with $ 61.32 for nuclear power, $ 53.42 for coal and $
49.66 for natural gas. For now, advocates are pleased that pocketbook concerns are generating
renewed interest in green power.

Wind, solar, geothermal and other green power sources have long been championed
by people worried about smog and global warming, but until recently they were
too costly to compete. But the surging cost of fossil fuels is changing the
economics of the energy market.
"Rising fossil fuel prices are making renewable energy more competitive in
the power market," said Steve Taub, an alternative energy analyst at
Cambridge Energy Research Associates.
Renewable energy can't offer much relief to drivers and companies seeing their
profits evaporate because of skyrocketing oil prices, because viable green
alternatives to gasoline are hard to find. Biofuels such as ethanol and
biodiesel aren't widely available, and hydrogen-powered cars aren't expected to
hit the market for years.
But in the electricity market, green power, especially wind, is already
competing with traditional sources. At today's average wholesale prices, wind
costs 4.2 cents per kWh, compared with 4 cents for coal, 6.8 cents for natural
gas, 9.1 cents for oil and 10 cents for nuclear power, according to Kyle Datta,
managing director at the Rocky Mountain Institute, a research group focused on
eco-friendly business.
"They're never going to run out, but the ability to match supply to demand
may already have run out, especially for oil," said Stephen Leeb, president
of Leeb Capital Management and co-author of "The Oil Factor," which
predicts that oil could hit $ 100 a barrel by 2010.
"We should treat the prices as a warning that we need to act to promote
energy efficiency and renewable energy," said Ralph Cavanagh, an energy
expert at the Natural Resources Defence Council. "They represent a terrible
threat to the vitality of the United States."
Some major oil companies, particularly BP, are investing to develop alternative
fuels such as hydrogen, wind and solar. BP Solar, a BP subsidiary, has grown
about 30 % annually, boosted by government incentives that make solar
competitive in sunny states such as California, said spokeswoman Sarah Howell.
"BP invests in it because we see it as a long-term business that will grow
ever stronger," Howell said.
Increasingly, solar power is gaining popularity with individual homeowners and
businesses that want to generate their own power, but it isn't used much by
utilities. Geothermal energy is limited by geography, and biomass is still being
developed as a reliable fuel source.
Wind, which makes up less than 1 % of the nation's energy supply, is the
fastest-growing source of renewable power. Over the past five years, large-scale
wind farms have been builtin Texas, California, Kansas, Wyoming and other
states.
Advocates point to wind's numerous advantages: Wind is free and inexhaustible,
it doesn't generate smog or greenhouse gas, and its price is more stable than
its chief competitor, natural gas. The downside is that the wind doesn't always
blow, and not all regions have strong wind resources.
Despite renewed attention on renewable energy, some analysts say the current
spike in fossil fuel prices won't significantly boost the alternative energy
market. They say governments must promote renewable energy, raise fuel
efficiency standards and encourage investment in research.
"It brings attention to the need to diversify America's energy
portfolio," said George Douglas, spokesman for the National Renewable
Energy Laboratory in Golden, Colorado. "It raises people's awareness of the
cost of energy and where energy comes from."
