Hiding from the truth about 100% renewable energy

The French government has joined the Australian government in ignoring their own reports that say a transition to 100% renewable energy is feasible and involves little extra cost.

Mediapart obtained a report from the French government’s own environment and energy agency body ADEME that showed to use 100% renewable energy by 2050 is materially and technologically feasible and would cost relatively little more than the current electricity supply which is 75% nuclear.

Yet the government is holding a conference with the theme “40% of renewable electricity by 2050: is France ready?” A presentation on 100% renewables was mysteriously removed from the agenda at the last minute, but Mediapart obtained a copy of the study.

Flamanville 3 nuclear reactor under construction

Image (EDF): The Flamanville 3 nuclear reactor was estimated before construction to cost 3.3 billion Euros, but by its intended completion date in 2012, this had blown out to 8.5 billion Euros, with the completion date pushed back to 2016.

The study finds that President Francois Hollande’s target of reducing nuclear from 75% to 50% by 2050 would only be slightly cheaper for consumers than their 100% renewable scenario, sinking claims by pro-nuclear advocates that their favourite tech is the cheapest.

Some people just don’t want to hear the good news. Does this sound familiar?

Dispelling myth of energy payback of renewable energy systems

It’s sometimes suggested that the life-cycle energy inputs of  renewable technologies can well exceed their outputs – an argument that some attempt to use against wind turbines, as well as solar PV modules. In this article by Mark Diesendorf  we find a clear explanation of just what ‘life-cycle energy inputs’ are, how they may be calculated, and how energy payback periods of various technologies compare. The figures may surprise you, and yet another myth bites the dust!

Published by Renew Economy. View original article 

One of the many myths propagating about renewable energy (RE) systems, especially solar photovoltaic electricity, is that the life-cycle energy inputs are greater than or comparable with the lifetime energy outputs. Is it generally true and, if not, under what special circumstances would it be reasonable?

Life-cycle energy inputs for solar PV modules are now greatly reduced

Wind Economics: Case for wind energy strengthens further

Published by Wind Power Monthly. View original article.

WORLDWIDE: A new report comparing generation costs for different technologies on a global basis confirms wind’s competitiveness.

Screen Shot 2013-10-10 at 9.02.38 AM

In its Renewable Energy Medium-Term Market Report 2013, the International Energy Agency (IEA) compares all electricity-generating technologies and suggests that the minimum global price for onshore wind is about $50/MWh, which can only be bettered by geothermal and hydro in favourable locations, and coal and gas in some locations with cheap access. The IEA suggests the generation cost range for onshore wind is $50-160/MWh, with offshore wind at $150-340/MWh. Coal is placed at $40-90/MWh and gas at $40-130/MWh. This confirms once again that the cheapest wind can now compete with both gas and coal. Continue reading “Wind Economics: Case for wind energy strengthens further”

Wind Power Helps to Lower Electricity Prices

Published by Center for American Progress. View original article.

By Richard W. Caperton is the Director of Clean Energy Investment at the Center for American Progress.

A section of this report on negative prices has been removed because of flawed data.

saving_electricityHere’s something that shouldn’t surprise anyone: A company that benefits from high power prices is lobbying for policies that would raise power prices for consumers. What should surprise everyone, however, is the sheer audacity of their effort: using a deeply flawed study to argue that tax incentives for wind power are “distortionary” while arguing for the exact same incentives for their preferred technologies.

Earlier this summer Exelon Corporation, a large U.S. power generator and utility operator, began quietly lobbying against extending the production tax credit for wind energy. Its effort gradually became more public, and has now erupted into a full-scale war on the wind industry. In fact, the American Wind Energy Association terminated Exelon’s membership in the association. And Exelon is now touting a study by the NorthBridge Group, an economic and strategic consulting firm, that purports to show that the production tax credit is deeply harming consumers by—get this—saving them too much money.

Exelon’s argument is strange but has gained some traction among wind energy opponents on Capitol Hill. Sen. Lamar Alexander (R-TN) and Rep. Mike Pompeo (R-KS), for example, just penned an editorial in The Wall Street Journal parroting NorthBridge’s claims. Fortunately, though, the facts are on the side of wind power.

Offshore wind farm for Japan’s Fukushima province

In Japan, a new floating wind turbine is being trialled off the coast of the disaster-struck Fukushima province. About this time last year, as many of us were still in shock from the footage of the terrifying tsunami – and chilled by the unfolding catastrophe at the Fukushima nuclear power plant – Japan’s wind farms were still producing energy; in fact they were basically unaffected by the tsunami and earthquake. The following is from The Denki Shimbun, a daily energy newsletter. Floating offshore wind farm demonstration project in Fukushima Mar. 09, 2012 TOKYO –The demonstration research project of a floating … Continue reading Offshore wind farm for Japan’s Fukushima province

Addressing public concerns about wind power

A new research paper from the UK-based Centre for Sustainable Energy re-visits many of the myths about wind power. As CSE says “Wind turbines are beautiful to some, monstrous to others; but shouldn’t we be able to debate the issues in an informed and constructive way?” Thanks to Dave Clarke for spotting this one. CSE research paper aims to raise level of debate CSE has today published a research paper that addresses some of the misconceptions surrounding wind energy. ‘Common concerns about wind power’ draws on peer-reviewed articles and government-funded analysis, and was written in response to requests from community … Continue reading Addressing public concerns about wind power

Wind is Japan’s strongest alternative to nuclear

This article comes from New Scientist, author: Andy Coghlan TWO months after the explosions and radiation leaks at the Fukushima Daiichi nuclear power plant in Japan, the prime minister, Naoto Kan, has announced that the country will not build any new reactors. If Kan really means it, the government will have to abandon the plans for expanding nuclear power it adopted only last year. To make up the energy shortfall, Kan has set the ambitious goal of using renewables. That is most likely to mean wind, according to a report released last month by the Ministry of the Environment. There … Continue reading Wind is Japan’s strongest alternative to nuclear

Germany, Italy shift focus from nuclear to renewables

The following is taken from the Platts Renewable Energy Report (May 2011). It has been edited for brevity. An interesting quote about wind energy: “Wind energy is considered to have the greatest potential for swift, cost-efficient expansion of renewable electricity generation”. Germany, Italy shift focus from nuclear to renewables A month after the earthquake and tsunami that struck northern Japan crippled  the Fukushima nuclear complex and triggered fears of a catastrophe, Germany and Italy have taken steps to swiftly move from nuclear energy to renewable resources. Germany’s government plans to have new legislation drawn up as early as June to … Continue reading Germany, Italy shift focus from nuclear to renewables

world wide installed capacity from renewables passes nuclear

This comes from GreenPages. World First: Report on New Energy Capacity Shows Renewable Supersedes Nuclear In 2010, for the first time, worldwide cumulative installed capacity from wind turbines, biomass, waste-to-energy, and solar power surpassed installed nuclear capacity. Even before the disaster in Fukushima, the world’s nuclear industry was in clear decline, according to a new report from the Worldwatch Institute. The report, which Worldwatch commissioned months before the Fukushima crisis began, paints a bleak picture of an aging industry unable to keep pace with its renewable energy competitors. “The industry was arguably on life support before Fukushima. When the history … Continue reading world wide installed capacity from renewables passes nuclear
