The bright future of solar powered factories

by

Most of the talk about renewable energy is aimed at electricity production. However, most of the energy we need is heat, which solar panels and wind turbines cannot produce efficiently. To power industrial processes like the making of chemicals, the smelting of metals or the production of microchips, we need a renewable source of thermal energy. Direct use of solar energy can be the solution, and it creates the possibility to produce renewable energy plants using only renewable energy plants, paving the way for a truly sustainable industrial civilization.

Cut energy demand to meet shortage

by

Between April last year and March this year, the world was struck by three Black Swan events that ‘everyone’ knew would happen, yet, strangely, seemed unprepared for when they did. The Gulf of Mexico oil leak, the political upheavals in the Middle East and North Africa (Mena) region and the earthquake-tsunami-nuclear tragedy in Japan are already inflicting history-altering impacts, not the least, because they have significantly and immediately reduced the world’s supply of cheap energy.

Nuclear delusions

by

The heating of Earth remains the most urgent symptom of humanity’s mismanagement of our technological civilization. Desperately seeking answers for a low carbon energy regime, some observers propose a “nuclear renaissance” to replace hydrocarbons. Nuclear companies, nations, and advocates offer nuclear as a possible “low-carbon” energy path. However, the evidence in hand shows that nuclear energy is not the solution to humanity’s energy needs that many hope for. Here are the reasons…

La transición alimentaria y agrícola

by

A spanish translation of the Post Carbon Institute report ‘The Food and Farming Transition: Toward a Post-Carbon Food System’.El sistema alimentario norteamericano descansa sobre unas bases inestables de insumos de combustible fósil masivos. Ante la disminución de las reservas de combustible el sistema alimentario se debe reinventar. El nuevo utilizará menos energía, y la energía que use vendrá de fuentes renovables. Podemos empezar la transición al nuevo sistema inmediatamente mediante un proceso de cambio planificado, graduado y rápido. La alternativa no planificada –la reconstrucción desde la base tras el colapso- sería caótica y trágica.

ODAC Newsletter – July 15

by

The world could soon be short of oil again, despite the worsening fiscal crisis, says the IEA. Although the turmoil in Europe threatened to engulf Italy – with the world’s third largest bond market – and the US budget standoff threatened its AAA credit rating, the Agency raised its 2012 oil demand growth forecast by 270,000 barrels/day.

The end of cheap coal

by

World energy policy is gripped by a fallacy — the idea that coal is destined to stay cheap for decades to come. This assumption supports investment in "clean-coal" technology and trumps serious efforts to increase energy conservation and develop alternative energy sources. It is an important enough assumption about our energy future that it demands closer examination.

Tin production — A classic case of limits to growth

by

The tin production story is out there is in plain sight, but only those directly involved in supplying the tin ore, refining it or consuming tin metal are paying any attention. Bloomberg’s Bear Market in Tin Ending as Shortages Mean PT Timah’s Profit Advances 55% explains what’s going on now, and what’s been going on for years now…
