Quokka, Germany's installation costs are aproaching $ 2 a watt for
point of use solar.
Many Indians are installing
point of use solar to help cope with an unreliable grid and save fuel costs on diesel generators.
This point of use solar capacity reduces demand for grid electricity and so reduces the wholesale price as lower demand results in lower prices.
As
point of use solar competes at retail prices and not wholesale prices, this certainly makes it look as though
point of use solar is cheaper than nuclear in India, especially when the costs of insurance etc. for nuclear are included.
As for
point of use solar in Germany, get back to me when it generates as much low emission electricity as the nuclear capacity that has recklessly been shut down or is on death row.
So even $ 1.6 billion a gigawatt nuclear power won't be able to compete with
point of use solar as it competes with retail prices, not wholesale prices.
For the very last time —
point of use solar is little more than a distraction from the main game which is to shut down coal.
I assume that South Korea will be able to install solar as cheaply as Germany and looking at South Korean capacity levels for solar and seeing that the cost of money to homeowners is about 5 %, the cost of
point of use solar in South Korea should be about 11 cents a kilowatt - hour.
If the cost of solar electricity is higher than the wholesale price, but lower than the retail price then
point of use solar capacity will be installed as it saves people money on their electricity bills.
So, it appears
that point of use solar will be competitive in South Korea once they reach German installation costs.
You see, it works like this, because of an unreliability of grid power, because it saves money on electricity bills, or because there is no electricity grid, people purchase
point of use solar.
The future certainly includes
point of use solar, CHP natural gas, and fuel cell power generation.

use of solar power to heat communal shower blocks, wildlife areas, recycling
points etc. - Water and power usage during the holiday is often less than in a hotel.
The new edict for Oahu mostly focuses on grid circuits where power available from rooftop
solar reaches or exceeds 100 percent
of the minimum daytime load, the low
point of the total power that customers on a circuit are
using.
The IRIS team will
use information from other satellites that observe the whole sun, such as Japan's Hinode and NASA's
Solar Dynamics Observatory, to identify active areas
of the sun and
point IRIS toward flares as they grow, when it will obtain spectra every two seconds.
If they would
use a more realistic climate transfer sensitivity
of 0.11 K / Wm -2, or even somewhat higher (0.12 or 0.13) for the long - term, and
use trends instead
of smooth curve
points, they would end up with
solar contributions
of 10 % or less for 1950 - 2000 and near 0 % and about 10 % in 1980 - 2000
using the PMOD and ACRIM data, respectively.
Normally, NASA watches for this wild space weather
using solar observatories like SOHO and the STEREO mission, a pair
of solar - orbiting satellites
pointed at the Sun from two different angles.
Solar power emits no greenhouse gases, no carbon dioxide and, when distributed, can provide power at or near the
point of use without turning our cities into smog factories.
Because the telescope can also be
pointed toward the sun, others have suggested shifting its field
of view and
using it to study objects in the inner
solar system, such as asteroids that might be heading toward Earth.
As you might hope, «Alan Smithee» is only
used in exceptional circumstances, and most
of the movies credited to the non-existent director are rightly forgotten: Mark Harmon / Robert Duvall actioner «Let's Get Harry» (actually helmed by «Cool Hand Luke» director Stuart Rosenberg), Jon Cryer comedy «Morgan Stewart's Coming Home,» ropey Charlton Heston sci - fi «
Solar Crisis» (originally by «Vanishing
Point» director Richard C. Sarafian), with Dennis Hopper's «Catchfire,» starring Jodie Foster, perhaps being the best known example.
In the description
of the DE200 planetary ephemeris, it is
pointed out that, contrary to all the other objects in the computation which
use the
Solar system barycentre, the orbit
of our own moon is computed relative to the Earth - Moon barycentre, because then, the orbit integration will behave nicer numerically — which is good, as the Moon is an object
of special interest.
; or maybe in a sense we do, but they could be
of either the political / social or technological sort; the more the better, but just political / social could work okay (although that would work partly by boosting R&D to continue technological progress, but I'm not sure if that's necessarily breakthroughs (it wouldn't surprise me if someone got a zinc phosphide, CZTS, or pyrite
solar cell to work economically at some
point in the future, or
used light - trapping to make c - Si cheaper and more efficient, or... — it would surprise me if it happenned tomorrow, but...).
I got to spend some time recently trying out a review unit
of the MiPow Playbulb
solar garden light, and after
using it for a bit, I can honestly say that while this device has its weak
points (don't they all?)
The weakest
point of the device that I could see is that the Playbulb garden light is only chargeable via the
solar cell, which is not necessarily a bad thing if it's only meant to be
used outside, but which seems to be a drawback if you want to
use the device inside for long periods.
In post # 40, CobblyWorlds
points to a recent analysis by Perovich et al. (2008), which
uses calculations
of solar energy input to the Arctic Ocean to assess the melting last summer.
There is, however, an interesting alternative.Tubular skylights, such as the ones shown here from Discount
Solar, allow sunlight to find its way to any
point in your home
using a system
of reflective tubes.
Some
of these shortcomings can be overcome, such as by buying a battery pack for convenience (in order to charge the battery during the day, and to then
use the battery pack to charge other devices at night), but some
of the weak
points can make the products an almost complete waste
of money, such as ones with a
solar panel or cells that are too small to be practical for everything except adding a little boost to a device's battery (which, to be fair, can be very useful indeed if your device's battery is completely flat).
Because PV panels are able to capture more
solar energy when they are
pointed directly at the sun, installers may configure systems to optimize output by adjusting the orientation and tilt
of a system, or by
using mechanisms that track the sun as it traverses the sky.
There has been growing tension between the electric utility industry and the
solar industry — specifically the part
of solar industry that is focused on distributed, or
point of use,
solar installations.
The accelerating pace
of adoption
of solar panels for distributed generation (installed at the
point of use, rather than sold into the power grid) and the downward trend
of module prices have created exuberance over the industry's future.
The
point about, say
solar panels, is that they
use a fraction
of the energy
used to build, run and decommission conventional power stations for the outputs.
When
used as a source
of energy to manufacture hydrocarbons such as methane and liquid fuels, as you
point out
solar panels can only do this in the daytime.
Indeed, we
point out specifically that the 1940s peak in the temperature record is not matched in the forced component
of our simulations regardless
of the
solar forcing
used.
I would have liked to see mention
of uncertainty that inherent in examining short term data, whether the end
points used introduces an element
of bias, whether the «pause» is on a much higher plateau
of warming than in the past, whether decadel cycles in ocean heat displacement may have interacted with the the known minimum levels
of solar activity (not modelled) to cause this «pause».
The power - generating equipment
used with a
solar dish can be mounted at the focal
point of the dish, making it well suited for remote locations, or the energy may be collected from a number
of installations and converted into electricity at a central
point.
In India, the government has advocated efforts to massively increase the
use of solar energy as a way to boost domestic
solar firms and has set aside a large chunk
of the
solar market for them in order to make that
point.
The other
point about renewable subsidies, at least for
solar, is that subsidies are provided directly to consumers in the form
of tax credits to install and
use solar panels.
Wouldn't relatively - small, easily - refueled, modular nuclear generators, sited below ground near
point of use and augmented with rooftop
solar in warm climes, enable «mini-grids» to power sub-communities and small towns without extensive transmission lines?
In an article breaking down the cost and break even
point of solar panels, Wise Bread
uses EnergySage pricing data to explain today's average gross cost per watt.
or even a sum
of sine waves — and NOT a straight line — were extended through the average
of the CET
using an 11 year
solar sunspot as a smoothing interval, when would the MWP, LIA, Dark Ages, and RWP show up as high and low
points?
«Climate models
used historic data for factors like greenhouse gas concentrations,
solar output, volcanic eruptions, air pollution, and other factors that can affect the climate through 2005 or so, but after that
point made assumptions
of how these would change in the future.
Some
of Monckton's talking
points included that CO2 is beneficial and a «life - giving gas on the planet,» that ocean acidification «is not a threat,» that climate change is
solar - driven, and that we should be increasing fossil fuel
use otherwise we are «depriving the poor
of inexpensive fuel.»
Since there aren't enough
solar homes in every neighborhood across the country at this
point, it's hard to
use this method to evaluate the value
of a
solar array.
You then asked «Or perhaps you can
point me to the dataset that shows, for several individual locations for the same period as the temperature set the: * CO2 concentrations (OK, we could
use Mauna Loa for that) * Aerosols (sorry, can't
use global records for that, there can be huge differences on a local scale) * Absolute humidity * TSI with correction for local albedo, including cloud albedo, and the place on earth» Well actually, I can and have for the USA in terms
of CO2, humidity (RH but AH also if you insist), and albedo, not to mention actual
solar surface radiation, and various other variables (eg windspeed), as I have previously reported here for quite a few locations, eg Pt Barrow.
Google also took advantage
of the first
solar eclipse in 99 years that will sweep the U.S. from coast to coast,
using this uncommon
solar event as an opportunity to launch Android 8.0 Oreo for maximum impact and lightheartedly
pointing out the visual similarities between a total eclipse and an Oreo.
But he
pointed out that adding
solar panels to an inefficient building doesn't reduce the amount
of energy being
used; it simply means the energy is coming from the sun instead
of oil or coal.
