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

In the run-up to the COP21 climate conference, one question becomes central: where will we find the solutions on the ground—and the people to implement them—to realize the renewed political ambitions on climate?
More than two decades ago, the world agreed on the need to confront climate change.
The U.N. Framework Convention on Climate Change (UNFCCC) emerged in 1992, spawning a variety of negotiating forums with the goal of preventing catastrophic impacts from planetary warming caused mostly by polluting societies.
It's easy to overlook the progress that has occurred since, because we still have so far to go. Droughts, flooding and cyclones that already seem to be the norm are just the latest warnings of what is coming, and preventing much worse requires immediate and aggressive action to drastically reduce greenhouse-gas emissions.
Tôi đang đứng bên bờ biển tỉnh Bến Tre ở Đồng bằng sông Cửu Long của Việt Nam. Tôi đang tự hỏi rằng liệu mấy tháng nữa liệu tôi còn có thể đứng đây được nữa hay không.
Mời các bạn hãy nhìn ra phía biển khoảng vài trăm mét, chỗ đó trước đây 3 năm vẫn còn là đất canh tác. Trong vòng 3 năm trở lại đây, ấp này đã mất khoảng một nửa diện tích đất đai. Vấn đề biển xâm thực chỉ là một trong những thách thức cam go mà nhà chức trách và người dân vùng Đồng bằng sông Cửu Long phải giải quyết.
I am standing on the shore of Bến Tre Province in the Mekong Delta in Vietnam. One of the first questions is, would I be able to stand here in a few months’ time?
If you look just a few hundred meters out to sea, that was cultivable land up to three years ago. In the last three years this village has lost half of its land. Sea incursion is just one of the complex challenges that the authorities and the people who live in the Mekong Delta have to juggle at the same time. So the Mekong Delta, the decisions that are made here are affected by the upstream decisions of hydroelectric planning, irrigation, and other freshwater use. By the time the water gets here, some of that freshwater which is needed is no longer available.
We’re about 16 months away from the 2015 UN climate meeting in Paris, intended to reach an ambitious global agreement on climate change. Now, more than ever, there is a need for innovation to scale up climate action.
The Bank’s Carbon Partnership Facility (CPF) is helping blaze that trail.
The role of the CPF is to innovate in scaling up carbon crediting programs that promote sustainable, low-carbon economic growth in developing countries. In its first set of programs, the CPF moved past the project-by-project approach to larger scale through the Clean Development Mechanism’s Programme of Activities, catalyzing investment in methane capture from landfills, small-scale renewable energy, and energy efficiency.
Right now, the carbon markets of the future are under construction in all corners of the world.
China is determined to pursue low-carbon development and is embracing the market as the most efficient way to do so. Wang Shu, the deputy director of China's National Development and Reform Commission, told us this week that he sees the "magic of the market" as the most efficient way to drive China's green growth.
Five Chinese cities and two provinces are piloting emissions trading systems with the goal of building a national carbon market. Chile is exploring an emissions trading system and focusing on energy efficiency and renewable energy. Mexico is developing market-based mechanisms in energy efficiency that could cut its emissions by as much as 30 percent by 2020. Costa Rica is aiming for a carbon-neutral economy by 2021.
Each of the countries pioneering market-based mechanisms to reduce their domestic carbon emissions are leaders. Bring them together in one room, and you begin to see progress and the enormous potential for a powerful networking domestic system that could begin to produce a predictable carbon price -- a sina que non for the speed and scale of climate action we need.
That's happening this week at the World Bank.
We raised glasses and cheered to the future success of Mr. Minh’s company. I had just visited his manufacturing facility where his company ASAMLED produces light-emitting diode (LED) lights for a variety of applications. A 40 person start-up and the only LED lighting company to manufacture over 90% of the final product locally, ASAMLED had the makings of Vietnamese clean tech success story. But as the day rolled on, we began discussing the real challenges the company and industry face. Starting an energy efficiency business in a country where energy is cheap and Chinese importers (who he called ‘screw-driver innovators’) are plenty, is not easy.
He told me how ASAMLED was conducting market tests with dragonfruit farmers. Using LEDs at night, dragonfruit production could jump from four harvests a year to nine – good news for the Vietnamese farmers who supply 40% of the fruit’s market in Europe. But he explained research like this was expensive and difficult to do with limited resources. According to him, the World Bank-run Climate Innovation Center could help him advocate his technology, inform consumers and access funding to market test a host of new LED applications.
