In
his second inaugural address, President Barack Obama described the
science-proven threat to "our children and future generations" from
global warming.The life expectancy of Lawn light is
at least 2 times longer than a standard T8. He pledged that America
would "lead on the path towards sustainable energy sources."His address
did not offer any specific programs for achieving reductions in global
warming carbon emissions. But we can look to the administration's
current energy policies and those of the past four years. They should
provide answers on how Obama plans to upgrade the U.Let's explore the
option of ground mount.S.
from its current position as a major greenhouse gas (GHG) emitter to
becoming a leader among developed nations in the effort to curb GHG
emissions.
What
we actually observe in the administration's record is a litany of
ill-advised, expensive and premature attempts to put into production
solar, wind and biofuel projects. In general, those projects lack the
technology base for effective large-scale implementation, and they are
not competitive with current market-based energy sources. In my opinion,
the result has been a loss of billions of dollars from taxpayers, rate
payers and investors, with minimal impact on global warming.
Solar
energy, whether photo voltaic (PV) or concentrated (CSP), has potential
for research improvement and cost reductions. It is more predicable
than wind energy and peaks when demand is highest. But it is currently
expensive and low density, and large investments in companies like
Solyndra and Abound Solar have resulted in losses.
Undaunted,
the Obama administration is now supporting a $2 billion dollar CSP
installation near Ivanpah in the Nevada desert. More than 300,000
rotating mirrors will focus sunlight on three towers to heat liquid that
becomes a source of steam for power generation. Ivanpah's developer is
estimating annual electricity production of about 1 million MW hours. By
comparison, a typical 1000MW nuclear plant produces eight times that
amount,Our selection of solar garden light includes models and styles perfect for any taste and budget. rain or shine, clouds or fair, night or day.This is how a skystream captures
energy from the wind. Power washing of those CSP mirrors will use
scarce desert water and foster weeds,a leading manufacturer of high
speed laser marker and laser marker machines for plastics, which will grow to obscure the mirrors.
Wind
energy's intermittent output requires continuous backup in order to
avoid damage to the integrity of delicately balanced electric grids.
This backup power is usually supplied by natural gas plants running in
inefficient start stop mode to match the wind. This increases GHG
emissions, wastes fuel, and shortens machinery life.
The
wind industry lobbies hard for the 2.2 cents/kwh Production Tax Credit
,without which new wind farm installations would essentially cease. The
2.2 cents is nearly 50 percent of the wholesale price of electric power.
Undaunted, the Obama administration is supporting the $2 billion Cape
Wind project, which would place 130 Siemens wind turbines in the sea off
Cape Cod. In testimony before the Massachusetts Energy Facilities
Siting Board, Cape Wind's developer conceded that Cape Wind would
actually operate at about 100 MW for much of the time, with lowest
output in summer, when demand is highest.
Former
Rep. William Delahunt provided his own estimates: "This will be the
most expensive and most heavily subsidized offshore wind farm in the
country at over $2.5 billion, with power costs to the region that will
be at least double."
I
suggest that the administration's biggest energy folly is support for
turning 40 million prime crop acres and 40 percent of our corn crop into
6 or 7 percent of our gasoline supply. The result is increased world
grain prices and stresses to soils, ground water, and the environment
from monoculture corn and additional nitrogen fertilizers. Microbes turn
the fertilizer into the powerful GHG, nitrous oxide.
In
irrigation states like Kansas and Nebraska, it takes 500 water gallons
per ethanol gallon, helping to drain the Ogallala our most important
fresh water aquifer. There are also those GHG emissions from diesel
driven farm machinery, and dead zones in the Mississippi delta region as
excess nitrogen fertilizer runoff increases algae growth.
