Energy Utilities Trying To Stifle Growth of Solar Power
An anonymous reader writes: Incremental improvements have been slowly but surely pushing solar power toward mainstream viability for a few decades now. It's getting to the point where the established utilities are worried about the financial hit they're likely to take — and they're working to prevent it. "These solar households are now buying less and less electricity, but the utilities still have to manage the costs of connecting them to the grid. Indeed, a new study from Lawrence Berkeley National Laboratory argues that this trend could put utilities in dire financial straits. If rooftop solar were to grab 10 percent of the market over the next decade, utility earnings could decline as much as 41 percent." The utilities are throwing their weight behind political groups seeking to end subsidies for solar and make "net metering" policies go away. Studies suggest that if solar adoption continues growing at its current rate, incumbents will be forced to raise their prices, which will only persuade more people to switch to solar (PDF).
Actually Tesla is really the wrong kind of battery - they are designed for high wattage (dis)charge, low mass, and low volume. None of which is relevant to your average home solar power system, and all of which come at the cost of considerable design compromises. Lithium batteries have short lifespans unless you're only using a fraction of their capacity, high environmental toxicity, and are extremely expensive. A more interesting contender is Aquion who are building a factory to build power-grid oriented saltwater batteries that are fairly nontoxic, don't mind being deep cycled, and are currently about the same price as lead acid (the cheapest rechargeable batteries available) while having 10x the projected working life (so effectively 1/10 the annual cost of lead acid). Sure they're every bit as heavy as lead-acid batteries while being even larger, but that's not really relevant to a stationary application.
--- Most topics have many sides worth arguing, allow me to take one opposite you.
My solution is to take some things of the grid. My outdoor lighting has been the first to go, soon to be followed by the swimming pool, finally followed by the workshop. Things considered "temporary" can be easily disconnected from the grid without violating code or running afoul of the banks.
When I move here in a few years I'll try for 100% disconnected. If I don't move I'll be paid off in 10 more years and can pull the plug.
It'll be interesting once we hit that balancing point of there being enough EV cars on the road today that gov't wakes up and restructures road funding so that every pays their fair share
If we do end up with a system involving paying a fair share, it would need to involve the weight of the vehicle, in which case the share of the cost by cars, electric or not, would be quite small considering the nonlinear effects on a road by heavier vehicles. Alternatively, one could just realize that many government fees are not about proportionately recovering costs, but influencing certain behaviors that have a variety of costs and benefits elsewhere.
Did you expect that factories and ships all ran on pixie dust?! China is putting their money where their mouth is, but conversions take time.
China is building out there solar very rapidly, more than doubling their capacity each year for the last 5 years (http://en.wikipedia.org/wiki/Solar_power_in_China). Oil and coal should be conserved for the things that solar and wind suck at, such as cargo ships. Predictable commutes of 30 miles are a travesty to waste gasoline on.
And [one in a hundred thousand, owns own house free and clear, grossing $70+k/yr] solar home owner says, but it works for me
A million homes in Australia have solar panels on their roofs as of right now. That's about one home in ten. Workers, pensioners, the unemployed, everyone - rich or poor, all benefiting from free energy. The installation pays for itself in five years, and comes with a twenty five year warranty. You Americans need to crawl out from under the dead hand of capitalism and join the free world.
Because there isn't really a good pie yet, they take far too long to pay off and can be dangerous to air traffic and wild life if they are A. in the wrong place, or B. installed incorrectly.
Oh, and if they don't have overspec'd components, they can cause a phenonom called "flicker" which is destructive of delicate electronics like your fridge, washing machine, A/C, and computer.
- Pilots have sunglasses.
- Wildlife have no problems with a flat piece of silicon that doesn't move. (Cars kill them by the millions though).
- And your electric circuit should have a fuse and other safety features that prevent fluctuations in the power.
How many of you trolls are volunteers, and how many are paid to troll by the coal/oil/gas lobbyists? This is just another scare tactic, just like everybody is now convinced that wind turbines kill birds, when in fact it is cats that kill birds.
Now move along, there is really nothing to see here.
