I have to say that I am gratified to see you say this:
$this->bbcode_second_pass_quote('', 'W')hile we all agree that there must, and will be a shift from non-renewable back to renewable
However, the rest of your argument is flawed for basically two main reasons; firstly, you do not acknowledge that raw materials to make RE systems can be recycled, nor do you realize that the new systems developed after serving their lifetime will be the product of new innovations and increased efficiencies. We are not going to run out of renewable resources! We will be returning to natural renewable energy sources like the sun and wind, which is in accord with exploiting sustainable natural systems. We discussed earlier that GDP growth has decoupled from energy consumption. As noted on page three (see part 1 old thread), in the US, this decoupling occurred within the last few years by a combination of a switch from coal to natural gas, greater energy efficiency, and a rise in renewable power (in order of importance). So your conclusions are false. As noted in the following article, this trend toward using RE is global - that is the scale of the RE development which is occurring now.
Locally-Controlled, Renewable Energy Championed as Key to Climate Justice$this->bbcode_second_pass_quote('', 'A')s progress at the UN climate summit in Lima, Peru has been reported as "slow" by many observers so far, green campaigners on Friday called on world governments participating in the talks to end their continued dependence on outdated fossil fuel- and nuclear-powered energy systems and urged investment and policies geared toward building clean, sustainable, community-based energy solutions.
"We urgently need to decrease our energy consumption and push for a just transition to community-controlled renewable energy if we are to avoid devastating climate change," said Susann Scherbarth, climate justice and energy campaigner at Friends of the Earth Europe. "We must stop subsidizing fossil fuels and put this money towards community-based energy solutions."
Backed by a new white paper by researchers at the What's Next Forum, Scherbarth and her colleagues at FOEI say that locally implemented and decentralized energy systems—including small-scale wind farms and distributive solar arrays that can feed-in to local power grids—are the key to pulling people out of poverty while also addressing the glaring crisis of runaway greenhouse gas emissions that are ruining the planet and the climate.
"We urgently need a transition to clean energy in developing countries and one of the best incentives is globally funded feed-in tariffs for renewable energy," said Godwin Ojo, executive director of Friends of the Earth Nigeria.
With rights activists across the world putting an emphasis on the idea of climate justice, Ojo put forth that Africans are not interesting in the fossil fuel industry's promises that more oil, coal and natural gas projects are the answer to the continent's energy needs or economic woes. Instead, he said, "Africans are pointing to real solutions to stop global warming and for environmental justice."
Among other policies, Ojo and his colleagues at Friends of the Earth have endorsed a proposal presented by African nations (pdf) earlier this year which called for an energy transformation focused on renewable sources, local control, and sustainable financing.
According to Sven Teske, a senior energy expert with Greenpeace, the debate that any nation must choose between economic prosperity and cleaner forms of energy should now be over.
"What’s giving this conference and the energy transition an added boost is that the costs of wind and solar energy have fallen considerably over the past few years," Teske wrote in a blog post as the talks began earlier this week. "In many countries renewable power plants are now cheaper and produce energy at a lower cost that fossil power plants. Nuclear energy is losing its allure as it proves to be expensive, dangerous and unsustainable."
Reporting last month from the New York Times showed that the overall costs of "providing electricity from wind and solar power plants has plummeted over the last five years, so much so that in some markets renewable generation is now cheaper than coal or natural gas."
And according to the Renewables 2014 Global Status Report (pdf), published in November, "Global installed capacity and production from all renewable technologies have increased substantially; costs for most technologies have decreased significantly; and supporting policies have continued to spread throughout the world."
