WWF study: Full energy use by renewables in 2050 possible

All of the world's energy needs could be provided cleanly, renewably and economically by 2050, according to a major new study by WWF.

Two years in preparation, The Energy Report breaks new ground with its global scope and its consideration of total energy needs including transport, and making adequate and safe energy available to all.

"If we continue to rely on fossil fuels, we face a future of increasing anxieties over energy costs, energy security and climate change impacts," said WWF Director General Jim Leape. "We are offering an alternative scenario - far more promising and entirely achievable.

"The Energy Report shows that in four decades we can have a world of vibrant economies and societies powered entirely by clean, cheap and renewable energy and with a vastly improved quality of life.

"The report is more than a scenario - it's a call for action. We can achieve a cleaner, renewable future, but we must start now."

The two-part report contains a detailed analysis and scenario presented by respected energy consultancy Ecofys, and an analysis by WWF. It shows that by 2050, power, transport, industrial and domestic energy needs could be met with only isolated residual uses of fossil and nuclear fuels - vastly reducing anxieties over energy security, pollution and not least, catastrophic climate change.

Energy efficiency in buildings, vehicles and industry would be a key ingredient, along with an increase in the energy needs met through electric power, renewably generated and supplied through smart grids.

"In this report we are very deliberately not making extravagant assumptions about the benefits of technologies yet to come," said Ecofys director Kees van der Leun. "This inherently means that this is a moderate estimate of the renewable energy future we could enjoy by 2050."

"At Ecofys we know that solutions for the global energy challenge are at hand. There are numerous systems that use energy more efficiently, allowing us to manage current energy sources more carefully. Moreover, we understand the opportunities in using the vast amounts of sustainable energy that surround us."

WWF-New Zealand Climate Change programme manager Peter Hardstaff said the report highlights the huge scope for New Zealand to benefit from our current and potential renewable energy supplies.

"New Zealand has more potential than most to advance this transition to safe, clean energy and by doing so, create new jobs and increase prosperity. With appropriate planning and development we could be in a position to showcase New Zealand-made technologies to the world."

Other benefits are savings from avoiding energy security conflicts, dirty spills and supply disruptions that are inherent in sourcing ever scarcer fossil fuels from more and more politically or environmentally challenging areas.

Importantly, The Energy Report scenario would see CO2 emissions from the world's energy supply sector reduced by over 80 per cent by 2050 - providing a high level of confidence that the average global temperature rise will be limited to the less than the two degrees Celsius threshold identified as presenting unacceptable risks of catastrophic climate change.

"We will live differently, but we will live well," said Jim Leape. "We must provide energy for all without imperiling our planet, and this report shows that we can."
