from NOW. They stupidly demand the end of nuclear power NOW.
Here's there's blabber on wind:
"it is an entirely realistic goal to for wind to provide 12 percent of the world's energy by 2020..."
I won't go into their perception of "entirely realistic" since they are strong on big mouths and low on delivery.
What would replace 20% of the world's energy NOW? Coal, even though global climate change is happening not in 2020, but NOW.
Then they skip inanely about "bioenergy," thusly:
Therefore, a sustainable approach to developing biomass energy systems must address concerns such as:
Burning wood from ancient forests
The use of genetically modified organisms
Intensive fertiliser and pesticide use
Loss of top-soil
An increase in salinity and toxic emissions
In addition, a standard certification system is needed for all the biomass fuel types.
It is important to note that none of these possible problems are fundamental to biomass technology, and they can be avoided with proper implementation. In areas with plentiful farmland, biomass can play a major role in supplying heat and electricity, and done properly biomass is a climate friendly solution to energy needs..."
No percentage given, but let's say 10% of the world's energy can come from bioenergy. Let's see 100%-12%-10% = 78% from fossil fuels.
As for the solar claims (PV), the claim is " From a current level of just 354 MW, by 2015 the total installed capacity of solar thermal power plants will have passed 5,000 MW, according to projections. By 2020, additional capacity would be rising at a level of almost 4,500 MW each year, and the total installed capacity of solar thermal power around the world could reach almost 30.000 MW - enough to power more than 30 million homes." Note these are magical solar "watts" with 20% capacity loading.
Thirty million homes...on a planet with billions of people...and no doubt given the price of PV, the thirty million wealthiest homes on the planet. Let's give them an (inflated) 5%.
So even with a generous acceptance of their fantasies, we see that they want to shut down 20% of the world's electrical energy, and replace 30% of it with renewables. This leaves 90% for fossil fuels. Do you really believe that a putative 10% reduction in coal demand will do shit for the mountains?
When we consider that Greenpeace, an organization brimming with conservatives, a conservative being a person without a new idea in decades, has been saying the same bullshit for thirty years, a conclusion is easily drawn:
Greenpeace, I repeat, is full of shit. They don't have anything to offer except power for rich people. They don't give a rat's ass about these mountains, and any reference to them is just window dressing.
It is very easy to criticize what others are doing when you are doing
nothing yourself. Greenpeace, which best I can tell an acrobatic company for dilettantes, has done zero for the environment. If you are for the environment, you are agitating
for nuclear power.
If by the way you are really interested in the cost to the environment and health (ie external costs) by energy, you can always access the EU study of the question:
www.externe.info
Here is table giving the preliminary results of this study, the units are in EUR-cent per kWh for electrical generation:
It's pretty clear that nuclear energy is by far and away the cleanest and safest form of
continuous, on demand energy, irrespective of what the circus clowns at Greenpeace have to say.
