Shifting the world to 100 percent clean, renewable energy as early as 2030 -- here are the numbers

Most of the technology needed to shift the world from fossil fuel to clean, renewable energy already exists. Implementing that technology requires overcoming obstacles in planning and politics, but doing so could result in a 30 percent decrease in global power demand, say Stanford civil and environmental engineering Professor Mark Z. Jacobson and University of California-Davis researcher Mark Delucchi.
To make clear the extent of those hurdles – and how they could be overcome – they have written an article that is the cover story in the November issue of Scientific American. In it, they present new research mapping out and evaluating a quantitative plan for powering the entire world on wind, water and solar energy, including an assessment of the materials needed and costs. And it will ultimately be cheaper than sticking with fossil fuel or going nuclear, they say.
The key is turning to wind, water and solar energy to generate electrical power – making a massive commitment to them – and eliminating combustion as a way to generate power for vehicles as well as for normal electricity use.
The problem lies in the use of fossil fuels and biomass combustion, which are notoriously inefficient at producing usable energy. For example, when gasoline is used to power a vehicle, at least 80 percent of the energy produced is wasted as heat.
With vehicles that run on electricity, it's the opposite. Roughly 80 percent of the energy supplied to the vehicle is converted into motion, with only 20 percent lost as heat. Other combustion devices can similarly be replaced with electricity or with hydrogen produced by electricity.

Jacobson and Delucchi used data from the U.S. Energy Information Administration to project that if the world's current mix of energy sources is maintained, global energy demand at any given moment in 2030 would be 16.9 terawatts, or 16.9 million megawatts.
They then calculated that if no combustion of fossil fuel or biomass were used to generate energy, and virtually everything was powered by electricity – either for direct use or hydrogen production – the demand would be only 11.5 terawatts. That's only two-thirds of the energy that would be needed if fossil fuels were still in the mix.
Fairy residence, tooth here!

. Our future is in ‘green energy’? “Presidents all the way back to Richard Nixon -- whose "Project Independence" promised to make America independent from foreign oil by 1980 -- were thwarted by short attention spans, other urgent problems and gyrations in the energy market.” After some 30 years and billions of dollars poured into alternative technologies, renewable energy now accounts for a mere 6.7% of our total.

Based on US Department of Energy, sources of energy used in the US:
39.2% petroleum, 23.3% natural gas, 22.4% coal, 8.3% nuclear, 3.6% biomass, 2.4% hydroelectric, 0.35% geothermal, 0.31% wind, 0.08% solar.
WTF are you talking about? Solar panels on DONESTIC land is DOMESTIC power unless I missed the treaty that Russia has made a claim to SUNLIGHT!!!
A coal power plant is built in America and runs on American coal. A windmill might be on our land but it is built in China. Coal plants are better for our economy.
G.E. windmills are built in China? Care to PROVE it?
A Plan to Power 100 Percent of the Planet with Renewables: Scientific American
A year ago former vice president Al Gore threw down a gauntlet: to repower America with 100 percent carbon-free electricity within 10 years. As the two of us started to evaluate the feasibility of such a change, we took on an even larger challenge: to determine how 100 percent of the world’s energy, for all purposes, could be supplied by wind, water and solar resources, by as early as 2030. Our plan is presented here.
Scientists have been building to this moment for at least a decade, analyzing various pieces of the challenge. Most recently, a 2009 Stanford University study ranked energy systems according to their impacts on global warming, pollution, water supply, land use, wildlife and other concerns. The very best options were wind, solar, geothermal, tidal and hydroelectric power—all of which are driven by wind, water or sunlight (referred to as WWS). Nuclear power, coal with carbon capture, and ethanol were all poorer options, as were oil and natural gas. The study also found that battery-electric vehicles and hydrogen fuel-cell vehicles recharged by WWS options would largely eliminate pollution from the transportation sector.
Our plan calls for millions of wind turbines, water machines and solar installations. The numbers are large, but the scale is not an insurmountable hurdle; society has achieved massive transformations before. During World War II, the U.S. retooled automobile factories to produce 300,000 aircraft, and other countries produced 486,000 more. In 1956 the U.S. began building the Interstate Highway System, which after 35 years extended for 47,000 miles, changing commerce and society.
Is it feasible to transform the world’s energy systems? Could it be accomplished in two decades? The answers depend on the technologies chosen, the availability of critical materials, and economic and political factors.
possible and probable are 2 different things.
A 100% changeover from fossil fuels to so called renewable energy will cost quadrillions of dollars.
once again we see the abandonment of the good for the perfect.
A doable and needed plan.

Yeah pretty cool when Reagan took down the solar panel that Carted put up on the WH. If we had followed through with his ideas we could be energy independent NOW. You do know Carter was a nuclear engineer right.
Raw Materials Handling -
The primary component of glass fiber is sand, but it also includes varying quantities of
feldspar, sodium sulfate, anhydrous borax, boric acid, and many other materials. The bulk supplies are
received by rail car and truck, and the lesser-volume supplies are received in drums and packages.
These raw materials are unloaded by a variety of methods, including drag shovels, vacuum systems,
and vibrator/gravity systems. Conveying to and from storage piles and silos is accomplished by belts,
screws, and bucket elevators. From storage, the materials are weighed according to the desired
product recipe and then blended well before their introduction into the melting unit. The weighing,
mixing, and charging operations may be conducted in either batch or continuous mode.
Glass Melting And Refining -
In the glass melting furnace, the raw materials are heated to temperatures ranging from
1500 to 1700°C (2700 to 3100°F) and are transformed through a sequence of chemical reactions to
molten glass. Although there are many furnace designs, furnaces are generally large, shallow, and
well-insulated vessels that are heated from above. In operation, raw materials are introduced
continuously on top of a bed of molten glass, where they slowly mix and dissolve. Mixing is effected
by natural convection, gases rising from chemical reactions, and, in some operations, by air injection
into the bottom of the bed.
Glass melting furnaces can be categorized by their fuel source and method of heat application
into 4 types: recuperative, regenerative, unit, and electric melter. The recuperative, regenerative, and
unit melter furnaces can be fueled by either gas or oil. The current trend is from gas-fired to oil-fired.
Recuperative furnaces use a steel heat exchanger, recovering heat from the exhaust gases by exchange
with the combustion air. Regenerative furnaces use a lattice of brickwork to recover waste heat from
exhaust gases. In the initial mode of operation, hot exhaust gases are routed through a chamber
containing a brickwork lattice, while combustion air is heated by passage through another
corresponding brickwork lattice. About every 20 minutes, the airflow is reversed, so that the
combustion air is always being passed through hot brickwork previously heated by exhaust gases.
Electric furnaces melt glass by passing an electric current through the melt. Electric furnaces are
either hot-top or cold-top. The former use gas for auxiliary heating, and the latter use only the electric
current. Electric furnaces are currently used only for wool glass fiber production because of the
electrical properties of the glass formulation. Unit melters are used only for the "indirect" marble
melting process, getting raw materials from a continuous screw at the back of the furnace adjacent to
the exhaust air discharge. There are no provisions for heat recovery with unit melters.

My question is WHY do so many people seem to be SO AFRAID of this idea?
Why does it strike FEAR into the hearts of conservatives? I mean I would think a CONSERVATIVE root word CONSERVE would want our Earth to be free from burning fossil fuel. Even the Bible thumpers.....Doesn't God say to care for the Earth?

In theory, about 2.2 million Btu
of energy are required to melt a ton of glass. In
reality, it takes twice as much energy because of
inefficiencies and loses. The glass industry consists
of four major segments: container glass (bottles,
jars, etc.); flat glass (windows, windshields,
mirrors, etc.); fiberglass (building insulation and
textile fibers); and specialty glass (cookware, flat
panel displays, light bulbs, fiber optics, medical
During this time, Ohio has lost about 200,000 manufacturing jobs. These jobs are not simply migrating to another region – they are going overseas and they aren’t coming back. This is because other countries do not have the high costs that we place on our industry, such as rising health care costs, litigation, regulatory burdens, taxes, unfair competition from China, and escalating natural gas costs.
“Almost all new production of chemicals and plastics will take place in the Middle East and Asia…Charles O. Holliday Jr., chairman and chief executive of DuPont Co., told investors in December that high energy costs will prompt the company to shift its ‘center of gravity’ overseas
Electrical heating is used exclusively in many
smaller specialty and fiberglass melting furnaces
because of its lower initial cost and low emissions,
even though energy costs remain high. Key
disadvantages of all electric furnaces are the high
energy cost and short furnace life. Electric furnaces
are rebuilt as often as every six months, but
because of their small size, down time is limited
to only about two days.
6.6 FIBER GLASS
The fiber glass industry is made up of two
primary markets: wool insulation and textile
fibers. Wool insulation is a short-fiber product used
by the construction industry. Textile fibers are a
continuous-fiber product principally used as a
polymer matrix composite reinforcement.
Together, the four major producers of wool and
the six major producers of textile fibers employ
about 16,000 workers. A typical producer can
operate as many as 27 glass melt furnaces. In 1991,
fiber glass made up 9% of all glass produced and
accounted for 21% of the total market value. In
1981, 71% by weight of all glass fiber shipped was
wool. Total energy consumption for the fiber glass
industry in 1991 was 59.5 trillion Btu,

Ever wonder what happened to T. Boone's plan to use prairie wind power to power the east coast? <line losses>
Ever wonder what happened to the massive solar plant in the Mojave Desert? <Pelosi, Boxer & Feinstein killed it>
Ever wonder why wind power isn't more plentiful? <need constant wind >13m/s to be cost-effective>
So where does all this leave "alternative energy". As a small percentage of the US power grid. The "smart grid" will do more to conserve power than alternative energy.
We had a lot of clean hydro-electric power, but dams are bad. <stupid political-correctness, hydro-power is a good thing>
Nuclear power is clean, and reliable. I think they are being built again. Good thing the old plants need to be replaced as they wear out.
