AFRICA - Which country boasts the world's fastest growing clean energy investment? Germany? No. United States? Think again. Jumping from a few hundred million dollars to $5.7 billion, South Africa recorded last year the world's highest growth in renewable energy investment, according to the U.N. Environment Program (UNEP). The spectacular surge, led largely by investments in solar power projects, comes as South Africa moves to reduce its dependency on coal, which accounts for around 86% of its energy. To achieve that, the country has set the ambitious target of generating 18 gigawatts (GW) of clean energy by 2030. As a result, a series of investments have trickled into the country, including Google's first foray into Africa's solar power market. The internet giant, which has spent more than $1 billion in renewable energy projects in the United States and Europe in recent years, announced in late May its decision to back the Jasper Power Project, a 96 MW solar photovoltaic (PV) plant in Northern Cape, with a $12 million investment. "We only pursue investments that we believe make financial sense," said Rick Needham, Google's director of energy and sustainability. "South Africa's strong resources and supportive policies for renewable energy make it an attractive place to invest." Abundance of sun Once completed, Jasper is expected to be one of the biggest solar installations in the continent, capable of generating enough power for some 30,000 homes. It's no secret that Africa has plentiful sunshine, with many parts of the continent enjoying daily solar radiation of between 4 kWh and 6 kWh per square meter. But it's no secret, either, that Africa has the world's lowest electricity access rates, with more than half of its countries experiencing daily -- and costly -- power outages. Amid such conditions, experts say investments in large-scale solar power projects could transform a continent faced with fast-rising populations and increasing demand for energy to support its economic growth. "Six out of the 10 fastest economies in the world (over the past decade) were in Africa, and that requires much more energy, at a faster-growing pace than we've seen before," says Frank Wouters, deputy director-general of the International Renewable Energy Agency. Ambitious projects And some countries have already taken notice. While South Africa is clearly setting the pace, projects are being announced across the continent as more countries look to unlock their massive solar potential. In late April, Mauritania launched what's described as Africa's biggest solar PV plant so far, a 15 MW facility that is designed to account for 10% of the country's energy capacity, according to its developers. In early May, Morocco began the first phase of the construction of a 160 MW concentrated solar power technology plant near Ouarzazate as part of the country's efforts to produce 2,000 MW of solar energy by 2020.
