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.

There are moments in history when America has turned its back on its principles and withdrawn from past commitments in service of higher goals. For example, US-Soviet Cold War competition compelled America to make a range of deals with unsavory and undemocratic figures across Latin America and Africa in service of geostrategic aims. The United States overlooked mass atrocities against the Bengali population in modern-day Bangladesh in the early 1970s in service of its tilt toward Pakistan, a relationship the Nixon administration deemed critical to its larger aims in developing relations with China. Then, of course, America switched diplomatic recognition
The international women’s soccer match between Taiwan and New Zealand at the Kaohsiung Nanzih Football Stadium, scheduled for Tuesday last week, was canceled at the last minute amid safety concerns over poor field conditions raised by the visiting team. The Football Ferns, as New Zealand’s women’s soccer team are known, had arrived in Taiwan one week earlier to prepare and soon raised their concerns. Efforts were made to improve the field, but the replacement patches of grass could not grow fast enough. The Football Ferns canceled the closed-door training match and then days later, the main event against Team Taiwan. The safety
The Chinese government on March 29 sent shock waves through the Tibetan Buddhist community by announcing the untimely death of one of its most revered spiritual figures, Hungkar Dorje Rinpoche. His sudden passing in Vietnam raised widespread suspicion and concern among his followers, who demanded an investigation. International human rights organization Human Rights Watch joined their call and urged a thorough investigation into his death, highlighting the potential involvement of the Chinese government. At just 56 years old, Rinpoche was influential not only as a spiritual leader, but also for his steadfast efforts to preserve and promote Tibetan identity and cultural
Strategic thinker Carl von Clausewitz has said that “war is politics by other means,” while investment guru Warren Buffett has said that “tariffs are an act of war.” Both aphorisms apply to China, which has long been engaged in a multifront political, economic and informational war against the US and the rest of the West. Kinetically also, China has launched the early stages of actual global conflict with its threats and aggressive moves against Taiwan, the Philippines and Japan, and its support for North Korea’s reckless actions against South Korea that could reignite the Korean War.
