• The UK and India are planning to improve connections between the world's electricity power grids.
  • The 'Green Grids Initiative' is backed by more than 80 countries.
  • It will allow areas with excess renewable power to send it to areas with deficits.
  • India's prime minister Modi has described these grids as 'critical solutions' to move the world into a 'clean and green future'.
  • The plan is part of a broader attempt to speed up the roll out of affordable low-carbon technology, covering more than 70% of the global economy.

Britain and India have introduced a plan to improve connections between the world's electricity power grids to accelerate the transition to greener energy.

Linking the grids would allow parts of the world with excess renewable power to send it to areas with deficits. For instance, countries where the sun has set could draw power from others still able to generate solar electricity.

The "Green Grids Initiative" at the COP26 climate talks in Glasgow, Scotland, was backed by more than 80 countries and could set a model for how rich countries help poorer ones to reduce their emissions and meet the goal of capping global warming at 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial norms.

"If the world has to move to a clean and green future, these interconnected transnational grids are going to be critical solutions," Indian Prime Minister Narendra Modi said in a statement.

U.S. independent energy expert Matthew Wald said the plan underscored how renewable energy sources need more transmission lines since they must often be built far from cities, unlike coal or gas-fired plants whose fuel can be shipped in.

But Wald said planners in various countries - including the former Soviet Union - have long dreamed of cheap transmission across time zones with limited progress. Although powerline technology has improved in recent years, Wald and others said the plan would require spending large sums.

"We're talking about transmission networks that will need to be undersea. They will need to cross mountain ranges. They'll need to cross deserts" said Kartikeya Singh, senior associate at Washington-based Center for Strategic and International Studies,

The official announcement of the trans-national grid plan did not include cost figures or funding details. Modi and British Prime Minister Boris Johnson had previously outlined the plan. On Monday, Modi had said India would reach net zero carbon emissions by 2070, two decades later than scientists say is needed.

Although seen as sceptical of efforts to slow climate change, Modi has attended the conference, while leaders of other major emitters, including China and Russia, are not attending in person.

The grids plan showed Modi willing to move the world's second-most populous nation away from fossil fuels as long as developed countries help, said Julie Gorte, senior vice president for sustainable investing at Impax Asset Management.

"Left to their own devices India is going to build coal plants," she said.

The plan is part of a broader attempt to speed up the roll out of affordable low-carbon technology, covering more than 70% of the global economy.

What’s the World Economic Forum doing about climate change?

Climate change poses an urgent threat demanding decisive action. Communities around the world are already experiencing increased climate impacts, from droughts to floods to rising seas. The World Economic Forum's Global Risks Report continues to rank these environmental threats at the top of the list.

To limit global temperature rise to well below 2°C and as close as possible to 1.5°C above pre-industrial levels, it is essential that businesses, policy-makers, and civil society advance comprehensive near- and long-term climate actions in line with the goals of the Paris Agreement on climate change.

The World Economic Forum's Climate Initiative supports the scaling and acceleration of global climate action through public and private-sector collaboration. The Initiative works across several workstreams to develop and implement inclusive and ambitious solutions.

This includes the Alliance of CEO Climate Leaders, a global network of business leaders from various industries developing cost-effective solutions to transitioning to a low-carbon, climate-resilient economy. CEOs use their position and influence with policy-makers and corporate partners to accelerate the transition and realize the economic benefits of delivering a safer climate.

Announcing the first five goals of the plan, dubbed the "Glasgow Breakthroughs", Johnson flagged targets to push clean power, zero emissions autos, near-zero emission steel, low-carbon hydrogen and climate-resilient agriculture.

The United States and the United Arab Emirates, meanwhile, began an initiative, with $4 billion in backing, to help farming adapt to climate change.
