Energy & Transportation
Are we at the dawn of a new energy revolution? It has never been more important to understand trends such as fossil fuel consumption, vehicles production, and the unprecedented growth in renewable energy, among others.
Feb 27, 2013
Smart Grid and Energy Storage Installations Rising
Driven by increasing shares of renewable energy in the electricity generation mix and by the need to update aging grid infrastructure, global investment in “smart grid” technologies rose 7 percent in 2012, totaling $13.9 billion worldwide. A smart grid is an electricity network that uses digital information and communications technologies to improve the efficiency and reliability of electricity transport. The increasing use of highly variable energy resources requires sophisticated control systems to facilitate their integration into the electricity grid.

Hydropower and Geothermal Growth Slows
Although hydropower and geothermal power are in very different stages of development, the market for these forms of electricity generation is increasing. These two sources are not subject to the variability that plagues wind and solar energy. Their greater reliability can thus be harnessed to provide baseload power. Hydropower is the older and more mature of the two technologies. Global consumption and installed capacity of hydropower continued to increase in 2011, reaching 3,498 terawatt-hours (TWh) and 970 gigawatts (GW) respectively. Total consumption has now increased each year between 2003 and 2011. But in 2011 the growth rate slowed, registering only a 1.6 percent increase from the previous year.

Global Coal and Natural Gas Consumption Continue to Grow
Global consumption of coal and natural gas continued to grow in 2011. Coal use increased by 5.4 percent to 3,724.3 million tons of oil equivalent (mtoe) from the end of 2010 to the end of 2011. Demand for natural gas grew by 2.2 percent in 2011, reaching 2,905.6 mtoe. Although oil remains the world’s leading energy source, coal and natural gas continue to grow in importance. Both are the primary fuels for the world’s electricity market. And because they often act as substitutes for each other, their trends need to be looked at together.

Continued Growth in Renewable Energy Investments
Emerging from the global economic recession, investments in renewable energy technologies continued their steady rise in 2011. Total new investments in renewable power and fuels (excluding large hydropower and solar hot water) jumped 17 percent—reaching $257 billion, up from $220 billion in 2010. In a year marked by falling costs for renewable energy technologies, net investment in renewable power capacity was $40 billion greater than investment in fossil fuel capacity. (Through the first half of 2012, however, total investment fell behind the impressive pace set the previous year, attracting slightly under $108 billion compared with nearly $125 billion in the first half of 2011.)

Auto Production Roars to New Records
Following a plunge in output triggered by the global economic crisis, world auto production is roaring back to new peaks. According to London-based IHS Automotive, passenger-car production rose from 60.1 million in 2010 to 62.6 million in 2011—and 2012 may bring a new all-time record of 66.1 million. Even though output of light trucks has declined, the combined numbers for passenger vehicles rose from 74.4 million in 2010 to 76.8 million in 2011 and may surpass 80 million in 2012.

Fossil Fuel and Renewable Energy Subsidies on the Rise
A recent projection places the total value of conventional global fossil fuel subsidies between $775 billion and more than $1 trillion in 2012, depending on which supports are included in the calculation. In contrast, total subsidies for renewable energy stood at $66 billion in 2010, although that was a 10 percent increase from the previous year. Two thirds of these subsidies went to renewable electricity resources and the remaining third to biofuels.

China Drives Global Wind Growth
In 2011, global wind power capacity topped out at 238,000 megawatts (MW) after adding just over 41,000 MW. This means that the global capacity grew by 21 percent in 2011—lower than the 2010 rate of 24 percent and markedly lower than the 2009 rate of 31 percent. Nonetheless, the world now has four times as much installed wind power capacity than in 2005, just seven years ago.

Energy Poverty Remains a Global Challenge for the Future
Acknowledging that many people in developing countries do not have access to affordable, reliable, and safe sources of energy, the United Nations General Assembly designated 2012 to be the International Year for Sustainable Energy for All. Expanding access to modern energy services for lighting, heating, refrigeration, cooking, water pumping, communications, and other services is essential for reducing poverty, improving health and education, increasing incomes, and enhancing rural livelihoods. It will be difficult to achieve a number of the internationally endorsed Millennium Development Goals without improving energy access.

Global Nuclear Generation Capacity Falls
Global installed nuclear generating capacity has declined in 2011, falling to 366.5 gigawatts (GW). As of October 2011 there were 433 nuclear reactors in operation around the world, compared to 441 at the beginning of the year. Just over 5.1 GW of installed capacity has been added since the beginning of 2010, with new connections to the grid in China, India, Iran, Pakistan, Russia, and South Korea. Over that same period, nearly 11.5 GW of installed capacity has been shut down in France, Germany, Japan, and the United Kingdom. More than 8.4 GW of installed capacity was shut down in Germany alone in 2011.

Global Oil Market Resumes Growth after Stumble in 2009
After falling 1.5 percent between 2008 and 2009 due to the global financial crisis, global oil consumption recovered by 3.1 percent in 2010 to reach an all-time high of 87.4 million barrels per day. About one third of this growth came from China, which now uses over 10 percent of the world’s oil. The United States, Brazil, Russia, and the Middle East accounted for an additional 48 percent of the increase. Meanwhile, consumption in the European Union decreased for the fourth consecutive year, falling 1.1 percent. The gap in oil consumption between countries in the Organisation for Economic Co-operation and Development (OECD) and non-OECD countries narrowed, with the two groups respectively accounting for 52.5 and 47.4 percent of total oil consumption in 2010.

Value of Fossil Fuel Subsidies Declines; National Bans Emerging
Global fossil fuel consumption subsidies fell to $312 billion in 2009 from $558 billion in 2008, a decline of 44.1 percent. The reduction is due primarily to changes in international energy prices as well as in domestic pricing policies and demand, rather than because the subsidies themselves were curtailed. The number also does not include fossil fuel production subsidies that aim at fostering domestic supply, which are estimated at an additional $100 billion globally per year.
