No, your assumptions are false. We can have economic growth solely with RE because most of the components are not that rare - silica for example. Decoupling of GDP from energy has already begun - we've discussed this before. In any case, we are both making such broad generalizations without knowing all details. That's why the arguments are weak. We haven't a clue what decisions are made in board rooms and governments on a day-to-day basis nor do we know all business plans. On top of that we don't have all knowledge published at our fingertips. We make generalizations based on scant knowledge. I'm hoping for the best; you want to put a spanner in the works. New knowledge emerges every day. For example:
Scientists use supercomputers to search for innovative answers to rare-earth supply needsDaily, new inventions are increasing the uses for rare-earths, but the mined and processed totals are falling short. Green energy technology needs rare earth materials for wind turbines, rechargeable batteries, and batteries for electric and hybrid vehicles. Although these elements are found throughout the world, as recently as 2012 the United States produced only 800 metric tons of the global production of 110,000 tons. This amount - far short of its needs - means the United States is relying on uncertain and costly imports for manufacturing and energy output. Researchers in the Critical Materials Institute (CMI) at the DOE's Ames Laboratory are looking for innovative answers to rare-earth supply problems. As an Energy Innovation Hub funded out of the Advanced Manufacturing Office in the Office of Energy Efficiency and Renewable Energy, the CMI mission is to diversify the global supply, discover substitutes, and invent new ways to re-use and recycle the rare-earths.
A team led by Ames Laboratory senior scientist Bruce Harmon - who recently retired - has been given up to 45 million core hours on Titan to look at multi-element materials. With its 27 petaflops (27,000 trillion calculations per second) processing power, Titan is able to examine the interactions of hundreds of thousands of atoms in three- and even four-element compounds.
"We finally have the computing capability to explore greater complexities using quantum mechanics – greater numbers of atoms, the possible crystal structures, and their properties," said Harmon. With the data from Titan's calculations, Harmon's team will select promising compositions as new magnetic materials to test.

BREAKING: California Governor Calls For 50 Percent Renewable PowerOn Monday, California Governor Jerry Brown gave the inaugural address for his unprecedented fourth term as governor of California. Brown used the speech as an opportunity to look back at how far the state has come since he was first elected 40 years ago, and to look ahead at the daunting tasks of the future.
Along the way California has been a nationwide leader and energy and environmental initiatives, and Brown used the occasion to lay out some ambitious targets as part of the speech’s broader focus on the importance of the state’s green agenda.
Brown listed three main goals to be accomplished within the next 15 years: First, to increase the amount of electricity the state derives from renewable sources from one-third to 50 percent. Second, to reduce petroleum use in cars and trucks by up to 50 percent. And the governor’s final goal is to double the efficiency of existing buildings and make heating fuels cleaner.
thinkprogressIndia’s solar dream fuelled by global trendsIndia’s plan to install 100 GW capacity of solar-generated electricity by 2022, a five-time increase from a previous target, only follows a global trend that has seen a sudden and massive jump in the deployment of solar power in the last four years.
The global installed capacity of solar electricity has increased by six times between 2010 and 2013. At the end of 2009, the total installed capacity was 23 GW. In the next four years, an average of about 28 GW was added every year, taking it to 135 GW by the end of 2013.
According to figures published by the International Energy Agency (IEA) a few months ago, more than 36 GW of new solar capacity was added in 2013, or about 100 MW per day (see box).
This explosion has led to projections for the future being revised upwards by significant amounts. In 2010, the IEA had said that by 2020, about 210 GW of solar electricity would be installed. Now, that target is likely to be achieved this year itself. In its latest projection, in 2014, the IEA said the total installed capacity in 2020 would easily exceed 400 GW.
indianexpressScotland Takes Lead in Race for the World's First Fossil-Fuel Free Electric GridConsider this: Wind power met all of Scotland’s electricity demand in November, with power to spare for export to the rest of the U.K., according to the environmental group WWF Scotland. In December, wind met country-wide demand for electricity in 25 of 31 days.
For the year, renewable energy and fossil fuels each supplied 32 percent of Scotland’s electricity, while nuclear energy provided 35 percent, according to the U.K. Department of Climate Change.
A new analysis commissioned by WWF Scotland describes how the nation of 5.3 million could eliminate fossil fuels and nuclear energy in just 15 years. How? By combining annual reductions in energy use by 1 percent a year while adding more wind and hydropower and improving the efficiency of the electrical grid.
