In India, for example, recent auctions to construct and run solar plants have seen prices for solar energy drop as low as for coal-fired power, tilting the economics of the electricity market towards renewables.
John Roome, senior director for climate change at the World Bank, said India had evolved from a decade ago when it was seen as part of the problem, insisting on its people’s right to develop above all else. In the last two years it has become a leader on clean energy and climate action, he said.
“They see the co-benefits between dealing with congestion, air pollution and other development needs, and they see the falling costs of the technology, and they see the opportunity for getting ahead of the curve to create new jobs in developing an electric vehicle industry, an air-conditioner industry, a battery industry,” he said while at a conference in Barcelona.
In November, the largest solar farm in the world was constructed in the southern Indian state of Tamil Nadu, taking the record from a facility in California.
But India and other big developing countries cannot make the transition alone, Roome said.
For example, February’s Indian solar power auction in Madhya Pradesh – where the cost of solar fell to a level equal with fossil fuels for the first time – was aided by World Bank help to acquire the land for a solar plant to be constructed.
Major improvements in energy efficiency, alongside new technologies, can enable poorer countries to grow in a green way, Roome noted, “but it’s going to take very concerted work between the policies, the incentives, the financing (and) focusing on developing the markets”.
He and other experts at the Innovate4Climate conference pointed to trillions of dollars now sitting in low-yielding investments or cash, looking for higher returns – much of which could be channelled into making economies greener and more resilient.
Currently less than 1 per cent of global investment is certified as “green”, Roome noted.
A mixed picture has developed in India where alongside a boom in solar power plants, the country is planning to build 370 coal plants that would ultimately breach its commitments under the Paris Agreement if constructed.
José Manuel Entrecanales Domecq, chief executive officer of Acciona S.A., a Spanish energy, water and infrastructure firm, said investors are “drooling” at the prospect of putting money into high-growth environments like Ethiopia.
But moving capital into those new markets depends on finding the right levers, and achieving a balance between risks and expected profit, he noted.
“You need to attract capital by giving stability and returns,” he said.
Gemedo Dalle, minister with Ethiopia’s Ministry of Environment, Forests and Climate Change, said his country has done its best to put in place a stable investment environment, including laws and policies.
Ethiopia estimates it will need more than $150bn (£116) to implement its national climate action plan by 2030.
As an industrialising nation, with the aim of becoming middle-income and carbon neutral by 2025, it has already built some modern infrastructure such as a light rail system in its capital – and the private sector is showing rising interest, Dalle said.
But the Horn of Africa country is not seeking to partner with companies offering old technologies, he emphasised.
“We are not looking for any kind of investment – we are looking for a climate-resilient, green economy,” he told the conference.
Roome said development banks could assist in working out what policy measures are needed to reduce the risks of investing in climate change measures in developing nations, and then structuring deals to support that – whether it’s a guarantee that power will be purchased as agreed or that communities will be resettled if displaced by a clean energy project.
Government and philanthropic funding should be used in a way that encourages private finance to enter the market, he said.
“We need to be much more rigorous about assessing the transformational value of any dollar that we spend,” he added.
In February the World Bank called out the West for failing to make the same gains in renewable energy generation that developing companies have achieved in recent years.
