Developing countries will need about $531 billion of additional investments in clean energy technologies every year in order to limit global temperature rise to 2° C above pre-industrial levels, thus preventing climate change’s worst impacts.

To attract investments on the scale required, developing country governments, with support from developed countries, must undertake “readiness” activities that will encourage public and private sector investors to put their money into climate-friendly projects.

WRI’s six-part blog series, Mobilizing Clean Energy Finance, highlights individual developing countries’ experiences in scaling up investments in clean energy and explores the role climate finance plays in addressing investment barriers. The cases draw on WRI’s recent report, Mobilizing Climate Investment.

The development of Thailand’s energy efficiency sector is an interesting case study. It demonstrates how strong government leadership combined with strategic support from international climate finance can drive the transition toward an energy-efficient economy.

In the early 1990s, Thailand’s economy was growing rapidly at 10 percent per year; the power sector was growing even faster. The government recognized that conserving energy would provide a low-cost way to meet its citizens’ rising demand for energy.
