Bill Gates On Energy
Sam the Nemesis
submitted an interview in Wired with Bill Gates on the future
of energy. Gates sees nuclear as the only
feasible option for base load generation. His views on the current
direction of energy funding are particularly distressing: "But the
economics are so, so far from making sense. And yet that's where
subsidies are going now. We're putting 90 percent of the subsidies in
deployment — this is true in Europe and the United States
— not in R&D. And so unfortunately you get technologies
that, no matter how much of them you buy, there's no path to being
economical. You need fundamental breakthroughs, which come more out of
basic
research."
Because he's one of the world's premier professional philanthropists with lobbyists and a research staff who's been involved with political and humanitarian advocacy full-time for ten years now?
Internet Explorer sucks and all, but Bill Gates is a very accomplished and intelligent man with a lot of influence. His opinions matter a great deal.
No it is not you *stupid fool*. Nuclear is the ONLY technology that actually manages its waste. The only one. If you care one bit about the environment, you would support nuclear precisely because of its waste management practices.
If fossil fuel energy managed all its waste, we would not be in the shit we are today. There wouldn't be catastrophic global warming. There would not be forest destroying acid rains. There would not be 1,000,000+ million people dying per year directly attributed to fossil fuel pollution and the diseases it produces. The ocean would not be polluted with mercury. Almost ALL lakes in the US are now so contaminated with mercury, it is not safe to eat fish from them! And the list goes on and on and on...
Nuclear waste is so *little* that even if you had to guard and monitor the dump and renew its containers for a billion years, it would still be very cheap. We are talking a few tons a year per reactor, if we don't do any r processing. Reprocessing could reduce this waste by 98% and provide more usable fuel) Simply a fund with $1-2 billion in it would be able to fund all the personnel in perpetuity simply from interest.
A coal plant burns *thousands of tons* of coal *per day*, producing hundreds of tons of toxic, carcinogenic waste *every day*, most of it going "puff" into the air you breath.
What's the total life-cycle cost comparison though?
With solar I see the following:
up front:
Mining raw material for the panels, batteries, and electrical converters
manufacturing the components in a low-security factory
transporting the components on standard truck
installing the panels and conversion equipment to an existing structure or building frames to install on bare earth
down the road:
cleaning the panels
maintaining the circuitry
replacing batteries
having an electrician or homeowner possibly replace individual components over time if things fail
end of life:
remove panels from frames
remove frames from structure or earth
remove switching equipment and batteries
send panels, frames, and switching equipment to recycler
send batteries to mild hazardous waste disposal for disassembly or recycling
Potential problems:
solar panels smashed en masse in a hail storm - solar is offline until panels are replaced and structure is back on grid power. If owner has insurance, that is used to pay for the replacement.
Batteries leak, owner stops storing power for overnight use and goes back on to the grid, and replaces batteries and cleans up acid spill
Absolute Worst Case- solar system causes a fire and the small structure burns.
Contrast to nuclear:
Startup:
Spend billions to build obtain land, fight local opposition, and build the plant.
spend millions to obtain ROW to install power transmission lines
Refine nuclear fuel in a high security factory
transport fuel in an expensive manner via truck convoy
employ dozens, if not hundreds of engineers and technicians to fuel, power up, and baby sit the reactor
down the road:
continue to employ dozens, if not hundreds of engineers and technicians to baby sit the reactor
spend millions to refuel reactor as necessary
spend millions to store spent nuclear fuel in the proper fashion, forcing it to stay cool until it's no longer generating its own heat
maintain security at the facility
end of life:
spend billions to decommission and clean up plant site
find solution for storage of spent fuel?
possible problems:
contaminated water spills posing an environmental hazard requiring expensive cleanup
mismanagement of the reactor leading to core meltdown and environmental contamination (worst case similar to Chernobyl, but without the graphite moderator)
natural disaster leading to core meltdown and environmental contamination (Fukushima)
attractive target for terrorism
I'm for solar subsidy, especially once solar panel efficiency exceeds 40%, which they're almost to on the newest panel designs, especially for structures that can receive solar panels without spoiling the appearance of the structure. Commercial and residential structures with flat roofs, retrofitting houses with the backyard side on the south (as to no put the panels on the roof on the front of the house, for appearance), and building new structures with solar in mind from the planning stages all appeal to me. Give subsidy for Photovoltaics with battery storage, grid-tie-in, and intentional islanding (leaving the structure powered by the PV or batteries but separating from the grid when the grid itself loses power) and suddenly every home becomes a mini power plant. It might even cost more per unit of energy than bulk production like at large power facilities, but it also reduces or eliminates a need for more wiring infrastructure, adds failover, and in places like the southern portion of the country, provides power when it's needed most, during the sunniest days when the air conditioning is cranked down and when power grids tend to fail due to a lack of capacity. A big enough solar installation at a house can power the whole house and can sell back to the grid easily.
If people are worried about safety, have cities implement an inspection regimen at installation, significant modification, and every ten years or so. Nothing really expensive, just something to make sure that everything is hooked up properly and safely.
Do not look into laser with remaining eye.
It comes down to a couple of simple questions. Firstly do you support a level of civilization that we currently have? That means all the things we use every day which requires energy. If you do, then you need lots of energy. If you don't then feel free to go back to the stone age and die from the next polio outbreak, cholera outbreak or famine. It really is that simple.
I ask you to do a couple of searches for:
1) How many people died as a result of Chernobyl?
2) How many people died as a result of Fukushima?
3) How many people died as a result of Coal mining?
4) How much radiation is released as a result of burning Coal?
Remember Chernobyl and Fukushima were not nearly as well designed as modern reactors. Unfortunately, we are forced to keep running these older designs because:
A) The public still wants to continue to live in a civilization with a standard of living similar to before while population increases, B) The public didn't want new nuclear plants built. Which would have allowed older plants to be retired.
C) The fuel rods at Fukushima should have been shipped to a long term storage facility scheduled for the U.S. but it was never built.
D) Chernobyl is a special case. Read the detailed report. The operators did the equivalent of taking a pressure cooker on a stove and filling it up with loads of water and then shoving it onto the exhaust of a jet engine.
So it's really that simple. Solar and Wind are all well and good, but they will not support the current level of civilization we enjoy. They may someday, and the use of them is not bad, but they simply wont cut it right now without deploying a huge number of them all over the place.
So if you want to keep your current standard of living, you need reliable base-load energy, and that energy needs to come from somewhere. Nuclear provides lots of energy and if you do the research you will find has actually - even accidents at Chernobyl and Fukushima included killed and harmed less people than fossil fuels. You may soon find more people die falling from wind turbines than Nuclear has killed.
So choose what you want. You may decide that you do want to live in a technological civilization that needs energy, but you don't want nuclear. Just don't be surprised if when you take a cold hard look at the numbers, you discover you actually made things worse by building huge wind farms and solar plants, and that your level of civilization collapses somewhat due to the costs.
