A recent article in the International Herald Tribune reminds us that money still talks when it comes to energy efficiency. According to the report, some of the largest enterprises in Ukraine are now investing hundreds of millions of dollars on new equipment and other measures to save energy. For many years businesses there enjoyed subsidized prices for energy, giving them little incentive to reduce the use of energy resources. The change of heart comes after Gazprom, Russia's state-owned energy company, ended decades of subsidized natural gas prices for Ukraine by doubling the cost of its gas exports in January. The price is expected to rise further next year, probably to world market prices. Interesting article; check it out.
