Energy Access

Hydropower in Vietnam: The right way to do it

People have been harnessing water to produce energy and perform work for thousands of years. The ancient Greeks used watermills to grind wheat into flour. Ancient Romans used the power of water to cut timber and stone. During the Han dynasty in China, hydraulically operated pumps raised water for crops into irrigation canals. Hydroelectric power is one of humankind’s oldest sources of energy.

Today it represents 16.6 percent of the world’s total electricity production while contributing 80% of the global renewable electricity mix.

Energy efficiency is a win-win for Africa

Here in Cancun, the discussions on energy efficiency made me reflect on the "big picture" about energy efficiency in Africa. For years this subject has been near and dear to my heart. As Director for Energy in the World Bank I saw how much there is to gain from solid energy efficiency plans in developing countries. I saw how increasing costs of energy can encourage serious action on efficiency. Now, as Director for Sustainable Development in Africa, I see how committed African countries are to improving energy efficiency and making smart use of demand-side management in their efforts to combat climate change.

 

This week I met with at least nine Ministers of Environment at the margins of the Cancun COP. Each one of them mentioned the importance of energy access but this was qualified with the fact that this energy must be clean and it must be used efficiently. For many of these governments, it is no longer enough to speak of clean energy in isolation. They prefer to think about it in the context of their integrated low carbon development agendas.

 

Given that 560 million people in sub-Saharan Africa do not have access to modern energy, African countries must expand power generation and access if they're going to reduce poverty. The trick is they will have to do it in climate-smart ways and this is where energy efficiency is an important win-win.
