Well the liberal media is elated that solar power in Florida just got a boost from the Public Service Commission (PSC).
In their editorial, "Fueling solar power"
the Sarasota Herald-Tribune says that, "The PSC, which regulates
utilities, approved a rule change that triples the credit for excess
solar energy that homeowners and businesses sell to power companies.
The PSC also expanded the size of solar electric systems that qualify
for the program and broadened the types of systems eligible to all
sources of solar energy, not just photovoltaic cells."
Here we
go, government subsidizing one thing over another and thereby trying to
impact the market. We believe, like Milton Friedman, that the
government solution to any problem is worse than the problem itself.
Our question is who is paying for the credits? We consumers are, of
course.
This is the same as subsidizing corn for ethanol in the
Midwest that has the environmentalists up in arms because the
fertilizer run off into the Gulf of Mexico has dramatically impacted
the "dead zone".
Something that the editorial board says however
is misleading at best and mis-information at worst. They state,
"Locally, the PSC's new rule could help attain a goal set last Friday
at a gathering of community leaders in Sarasota: that half of the homes
and buildings in Sarasota County will have solar water heaters in five
years. It was among the proposals made at the Environmental Summit for
Action, which drew 180 representatives of the local, state and federal
governments, community groups, businesses and environmental
organizations."
In fact, there were only 97 participants
remaining (not the implied 180) that voted on this "idea". According to
the SCOPE post summit e-mail we received this was an "idea" and not a
proposal. Most of the elected officials and nearly half of the
participants left during the lunch break and never saw, discussed or
voted on these "ideas". I have asked the Herald-Tribune to print a
clarification.
Of course, 97 participants at a limited access
summit do not equate to nor reflect the wants, needs and desires of the
other 370,000 residents of Sarasota.
In the editorial the cost
of implementing the "idea" that 50% of the "buildings" in Sarasota
County would have solar water heaters is mentioned - between $3,000 and
$5,000 for a single family home and much higher for larger systems.
What the editorial does not tell you is that a good standard water heater is around $300 and a tank less water heater system
sold by Tankless, Inc. a Sarasota based green manufacturing company
costs from $800 to $1,000 for a home with two adults, two teenage
children and two showers. A tank less water heater saves the average
home 70+% on their electricity bill because it only runs when used,
unlike a standard water heater that runs 24 hours a day.
What
they also don't tell you is that when the sun goes down or it is
cloudy, no hot water. What if you go to work early before the sun comes
up (remember daylight savings time) and want a hot shower? What if you
take a shower in the evening? We also know people who have put solar
powered pool heaters on their roofs and have serious problems with roof
leaks and roof maintenance afterward.
Here are some cons of solar energy from PowerPedia:
- Limited
areal power density: For electrical generation with photovoltaics, the
average irradiation power density is approximately 1 kW/m2 usable by 8-15% efficient solar panels.
- Intermittency:
It is not available at night and is reduced when there is cloud cover,
decreasing the reliability of peak output performance or requiring a
means of energy storage. For power grids to stay functional at all
times, the addition of substantial amounts of solar generated
electricity would require one or more of the following;
- energy storage facilities, such as Pumped-storage hydroelectric facilities, are needed to 'gapfill' low points in solar generation
- other renewable energy sources (i.e., wind, geothermal, tidal, wave, ocean power, etc) would need to be active, or
- backup
conventional powerplants would be needed. There is an energy cost to
keep coal-burning power plants 'hot', which includes the burning of
coal to keep boilers at temperature. Natural gas power plants can
quickly come up to full load without requiring significant standby
idling. Without changes in the energy supply and control system (such
as a shift to using current hydropower as nighttime/backup across wider
regions or the incorporation of more renewable power), few coal power
plants could be displaced, according to critics.
- Locations at high latitudes or with frequent substantial cloud cover offer reduced potential for solar power use.
- Solar cells produce DC which must be converted to AC when used in currently existing distribution grids. This incurs an energy penalty of 5-10%.
We
want to say that we are not against solar water heaters or the
companies that produce, market or sell them. We like companies that
make standard water heaters, and companies like Tankless, Inc. a local
green manufacturing company that builds, markets and sells tank less
water heater systems. These companies should be able to compete in our
markets on a level playing field.
Government should stay out of
the way and not try to pick winners and losers. Government certainly
should not impose upon the consumer one proposal or "idea" over
another. Consumers should look at the pros and cons and costs of each
system and make a decision.
