Renewable energy triggers sharply polarized views. For some, it is a costly white elephant; for others, it is humanity’s savior, promising to emancipate us (and our environment) from the “folly” of fossil fuels. So a hardheaded, credible and, above all, impartial analysis, which would provide a much-needed dose of pragmatism and realism to the debate, is long overdue.
The new report by the UN Intergovernmental Panel on Climate Change (IPCC), involving more than 120 scientists, economists and technology specialists, provides that long-overdue assessment. It adopts a global perspective and reconciles developed and developing countries’ interests, while weighing the broader economic, environmental and social issues at stake.
The summary, signed by representatives of the more than 190 countries meeting this week in the United Arab Emirates, concludes that renewable energy is an increasingly practical and highly promising option. Costs are falling — and are likely to fall even further as innovation accelerates and global demand for energy continues to rise.
The researchers have painstakingly sifted through more than 160 scenarios, including in-depth examinations of four. The most optimistic of these predicts that renewables could account for almost 80 percent of total energy supply by mid-century, thereby cutting greenhouse-gas emissions by about one-third.
Of course, only time will tell whether or not this figure can be reached. Some of the six renewable-energy technologies evaluated, such as those that generate electricity from the ocean, will require more research, development and incubation before they reach commercial maturity. However, others, such as wind, solar and geothermal are in some circumstances already cost competitive — or nearly cost competitive — with fossil fuels.
The IPCC report also underscores what some development experts and economists have been saying for years: Energy choices should take into account wider benefits. Renewables cut air pollution, which is costing the global economy billions of US dollars a year in health-care costs alone. Photovoltaics can be rapidly deployed in rural areas without the need to instal an expensive grid system — Bangladesh is a pioneering case in point. Moreover, we are only just coming to grips with the cooling costs of thermal power plants in terms of finite water resources — let alone the future price of unchecked climate change.
The ball is now firmly in the politicians’ court. The IPCC assessment points out that renewables are already growing. In 2009, installed capacity of wind and photovoltaics increased by more than 30 percent and 50 percent, respectively. However, the really big numbers are unlikely to be reached without the kinds of supportive public policies that have catalyzed the expansion of renewables in countries such as China and Germany.
Smart and forward-looking national policies are imperative. Kenya’s new feed-in tariff has triggered a rapid expansion of geothermal capacity, and, at 300MW, the largest wind-farm project in sub-Saharan Africa.
However, diverse national policies can achieve only so much. International policies, including the lending decisions of the World Bank and regional development banks, must evolve along with the strategies of the UN and bilateral donors.
The importance of moving forward on a new global climate agreement in Durban, South Africa, this year cannot be underestimated. A comprehensive agreement would bring certainty to the carbon markets and strengthen the various mechanisms that are already encouraging renewables in developing economies and pump-priming private-sector investments. The Rio Plus 20 meeting in Brazil next year is another opportunity to spark the transition to a global green economy.
Technical challenges remain: Seamlessly managing an array of very different energy sources will require investment in better national and regional grids. Yet the opportunities — to keep the global temperature rise this century to under 2?C, and to generate decent employment in clean-tech industries for millions of people — far outweigh the challenges. Clean and renewable energy will be an indispensable component of the fight against poverty worldwide.
The IPCC estimates that the costs of triggering a renewable revolution could range from US$3 trillion to more than US$12 trillion between now and 2030. That sounds pricey — and it is. However, fossil-fuel subsidies are currently running at more than US$600 billion a year, with barely a murmur of protest.
The IPCC report has provided a solid, scientific foundation for a low-carbon, resource-efficient future. Governments now have a clearer perspective on how to empower the lives and livelihoods of the world’s 7 billion people (9 billion to 10 billion by 2050), while keeping humanity’s footprint, including climate change, within the planet’s boundaries of environmental sustainability.

Taiwan stands at the epicenter of a seismic shift that will determine the Indo-Pacific’s future security architecture. Whether deterrence prevails or collapses will reverberate far beyond the Taiwan Strait, fundamentally reshaping global power dynamics. The stakes could not be higher. Today, Taipei confronts an unprecedented convergence of threats from an increasingly muscular China that has intensified its multidimensional pressure campaign. Beijing’s strategy is comprehensive: military intimidation, diplomatic isolation, economic coercion, and sophisticated influence operations designed to fracture Taiwan’s democratic society from within. This challenge is magnified by Taiwan’s internal political divisions, which extend to fundamental questions about the island’s identity and future
The narrative surrounding Indian Prime Minister Narendra Modi’s attendance at last week’s Shanghai Cooperation Organization (SCO) summit — where he held hands with Russian President Vladimir Putin and chatted amiably with Chinese President Xi Jinping (習近平) — was widely framed as a signal of Modi distancing himself from the US and edging closer to regional autocrats. It was depicted as Modi reacting to the levying of high US tariffs, burying the hatchet over border disputes with China, and heralding less engagement with the Quadrilateral Security dialogue (Quad) composed of the US, India, Japan and Australia. With Modi in China for the
The Chinese Nationalist Party (KMT) has postponed its chairperson candidate registration for two weeks, and so far, nine people have announced their intention to run for chairperson, the most on record, with more expected to announce their campaign in the final days. On the evening of Aug. 23, shortly after seven KMT lawmakers survived recall votes, KMT Chairman Eric Chu (朱立倫) announced he would step down and urged Taichung Mayor Lu Shiow-yen (盧秀燕) to step in and lead the party back to power. Lu immediately ruled herself out the following day, leaving the subject in question. In the days that followed, several
The Jamestown Foundation last week published an article exposing Beijing’s oil rigs and other potential dual-use platforms in waters near Pratas Island (Dongsha Island, 東沙島). China’s activities there resembled what they did in the East China Sea, inside the exclusive economic zones of Japan and South Korea, as well as with other South China Sea claimants. However, the most surprising element of the report was that the authors’ government contacts and Jamestown’s own evinced little awareness of China’s activities. That Beijing’s testing of Taiwanese (and its allies) situational awareness seemingly went unnoticed strongly suggests the need for more intelligence. Taiwan’s naval
