Economic Growth, The Financial Crisis, and Peak Oil For several years, a swelling subculture of commentators (which includes the present author) has been forecasting a financial crash, basing this prognosis on the assessment that global oil production was about to peak. (2) Our reasoning went like this: Continual increases in population and consumption cannot continue forever on a finite planet. This is an axiomatic observation with which everyone familiar with the mathematics of compounded arithmetic growth must agree, even if they hedge their agreement with vague references to "substitutability" and "demographic transitions." (3) This axiomatic limit to growth means that the rapid expansion in both population and per-capita consumption of resources that has occurred over the past century or two must cease at some particular time. But when is this likely to occur? The unfairly maligned Limits to Growth studies, published first in 1972 with periodic updates since, have attempted to answer the question with analysis of resource availability and depletion, and multiple scenarios for future population growth and consumption rates. The most pessimistic scenario in 1972 suggested an end of world economic growth around 2015. (4)

"In the first of a series of exclusive articles, James Gordon explores the latest developments in V2G systems and asks if the technology has the power to reshape global electricity distribution networks.…. It is the world's largest consumer of energy(1), and with over half of China's 1.3 billion population choosing to live in its sprawling and gridlocked super-cities, the demand for power has never been greater. But ensuring that the 680 million who live in China's megalopolises receive a steady stream of electricity is no easy task. However, while the solution - to install a network of long distance super-grids - has proved to be effective, it has come at great cost. This highly innovative smart grid infrastructure that the State Grid Corporation of China, has been specially designed to transmit ultra-high-voltage-direct-current (UHVDC) at over 600,000 volts to China's main population centres from rural areas rich in energy(2). America, India, Germany and Brazil are also incorporating UHDVC lines into their grids, but Britain, whose population is expected to grow from 64,875,165 (2015) to 77,568,588 by 2050(3), is only in the early stages of exploring the potential of the technology according to the Energy Networks Association. And while the UK's Utility giants may yet decide to invest billions of pounds in these high-tech super grids, a fully functioning next-generation Battery Electric Vehicle to Grid (V2G) charging system, located in Birmingham, the UK's second city, may mean they never need to. But how could this potentially game-changing technology, which has been installed at Aston University's European Bioenergy Research Institute (EBRI), one day save the National Grid and the tax-payer billions of pounds?"

Africa is the world's fastest urbanising continent. In 1950, sub-Saharan Africa had no cities with populations of more than 1m. Today, it has around 50. By 2030, over half of the continent's population will live in cities, up from around a third now. The fastest growing metropolises, such as Nairobi, Kenya's capital, are expanding at rates of more than 4% per year. That is almost twice as fast as Houston, America's fastest-growing metropolis.

The Yukon Environmental and Socio-Economic Assessment Board (YESAB) has recommended that the controversial Carmacks copper mine project can go ahead, providing that the Western Copper Corporation (TSX: WRN) complies with 148 conditions to mitigate potential adverse impacts. The tiny community of Carmacks with a year-round population of 500 is still considered an important service center for mining and for transportation, a century after it was a popular rest stop for the Yukon gold rush. However, members of the Little Salmon Carmacks First Nation want Western Copper to negotiate a better environmental engineering solution as part of an Impacts Benefits Agreement with the community. Located 38km northwest of the Village of Carmacks and 192 km north of Whitehorse in the Yukon Territory, the Carmacks copper project is planned to be an open-pit operation that will yield about 14,000 tonnes of copper cathode annually. Western Copper has targeted production to begin during the fourth quarter of 2010. Among the comments and concerns raised with the YESAB were routing of mining-related traffic, the heap leach detoxification process, sludge management, heap leach liner performance, and the estimates of closure costs. Among the comments and concerns raised with the YESAB were routing of mining-related traffic, the heap leach detoxification process, sludge management, heap leach liner performance, and the estimates of closure costs. The YESAB Executive Committee said it was satisfied that: Western Copper adequately consulted with the First Nations in whose territory, and the residents of any community in which the project will be located or might have significant or socio-economic effects; The project proponent provided sufficient information in the project proposal to allow for the assessment of potentially significant effects; Significant adverse environmental or socio-economic project and cumulative effects identified within the scope of the scre

This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

A new era for commodities Cheap resources underpinned economic growth for much of the 20th century. The 21st will be different. NOVEMBER 2011 * Richard Dobbs, Jeremy Oppenheim, and Fraser Thompson Source: McKinsey Global Institute, Sustainability & Resource Productivity Practice In This Article Exhibit: In little more than a decade, soaring commodity prices have erased a century of steady declines. About the authors Comments (2) Has the global economy entered an era of persistently high, volatile commodity prices? Our research shows that during the past eight years alone, they have undone the decline of the previous century, rising to levels not seen since the early 1900s (exhibit). In addition, volatility is now greater than at any time since the oil-shocked 1970s because commodity prices increasingly move in lockstep. Our analysis suggests that they will remain high and volatile for at least the next 20 years if current trends hold-barring a major macroeconomic shock-as global resource markets oscillate in response to surging global demand and inelastic supplies. Back to top Demand for energy, food, metals, and water should rise inexorably as three billion new middle-class consumers emerge in the next two decades.1 The global car fleet, for example, is expected almost to double, to 1.7 billion, by 2030. In India, we expect calorie intake per person to rise by 20 percent during that period, while per capita meat consumption in China could increase by 60 percent, to 80 kilograms (176 pounds) a year. Demand for urban infrastructure also will soar. China, for example, could annually add floor space totaling 2.5 times the entire residential and commercial square footage of the city of Chicago, while India could add floor space equal to another Chicago every year. Such dramatic growth in demand for commodities actually isn't unusual. Similar factors were at play throughout the 20th century as the planet's population tripled and demand for various resource

"Water is fundamental to human life and survival-our most fundamental instinct. Because of the forecasted challenges around sourcing adequate quantities of quality water, some feel future wars will be fought over water and not oil. Other challenges are related to the increasing population concentrations and climate-related weather events. This article considers water-related challenges arising out of urbanization and looks at how policies and technology can help make transition to more sustainable use of water work. "

""Our results indicate that areas of eastern Texas, Florida, the south-east and mid-Atlantic are areas where rapid population growth, acting in concert with a warming climate, will lead to a significant increase in exposure to heat extremes," says Jones."

BLYTH, NORTHUMBERLAND, UK, August 4, 2008. The New and Renewable Energy Centre (NaREC) in the UK and CENER, National Renewable Energy Centre of Spain are working together to find new ways of generating and distributing power from small-scale renewables within communities. The one year project will investigate ways to allow communities to generate and use their own power from renewable energy resources, in a reliable and cost-effective way. With increasing use of renewable energy sources, a significant amount of interest has developed across Europe in so-called 'smart-grid' systems better capable of transmitting and distributing power from different renewable resources in a reliable, flexible electrical network. The team is currently identifying existing communities within Spain and the UK with populations of between 10 and 25 000 which can be used as test subjects for 'smart-grid' renewable systems. The project aims to demonstrate the most appropriate technical solutions for integrating low carbon power generation technologies into a localised, community-based electrical system.

As designed, the cities will have a total of four times the geographic area of Hong Kong, three times the population of Dubai, and - so the Saudis claim - an economic output equal to Singapore's. The coastal King Abdullah Economy City is designed to house two million in an area twice the size of Hong Kong. Entirely funded by domestic and foreign private investors, this is the only one of the four planned cities that is currently under construction. Aside from the seaport and residential area, KAC will also house a sprawling industrial zone, a central business district, a sea resort, and a multi-university education campus.

Generally speaking, richer nations want permit allotments that track historic emissions rates - essentially locking in their economic advantage by awarding permits based on how much a country is already emitting. Developing countries, in contrast, want permits allocated according to population size, with every person on the planet getting equal emissions rights.

obots could fill the jobs of 3.5 million people in graying Japan by 2025, a thinktank says, helping to avert worker shortages as the country's population shrinks.

And it still has a long way to go. Today, barely one in five people around the world has access to the internet. Yet around three-quarters of the world's population lives within reach of a mobile network. In the decade ahead, many people, especially in developing countries, will have their first contact with the internet via a mobile phone.

Asia is using technology to build new models for delivering goods and services to its vast low-income populations. Many of those models will lead to powerful innovations for global markets.

"Despite growing concerns about an economic slowdown in the most populous nation, demand for new automobiles continues to be driven by rising vehicle ownership in tier 2 and 3 cities, especially for CUVs, which are advancing by 40% per annum. Luxury models also continue to outperform alongside rising wealth and as households shift their purchases from a weakening real estate market. "
