Can renewable sources provide the power the world needs?

In an interview given to the Financial Times earlier this year, Bill Gates suggested that governments should divert the massive sums of money currently channelled to renewable forms of power such as solar panels and windfarms to research and development. His view is that the cost of using such renewable sources to produce sufficient power for the world would be “beyond astronomical”. Instead, comparable investment in R&D could offer a chance of developing low-carbon technologies which could actually contribute significantly to the provision of global energy and represent a viable solution for reducing CO2 levels.

Diverting subsidies in many countries could be difficult, given that there are no subsidies as such, simply artificially inflated power prices. In addition, Bill Gates appears to have overlooked the low-carbon technologies that are already in use, and which could be expanded exponentially to contribute significantly to the production of power.

“The process of anaerobic digestion is a tried and tested technology that we employ to harness the gases naturally produced by organic waste material to deliver low carbon energy for power or fuel,” explains Richard Lilleystone, Gazasia CEO. “The process has three distinct benefits – making use of discarded material, reducing the emission of CO2 and other harmful greenhouse gases and providing low carbon energy.”
