Total consumption of marketed energy is expected to expand by 54% from 404 quadrillion Btu in 2001 to 623 quadrillion Btu in 2025
World oil reserves are expected to last for 45 years and gas reserves for 65 years.
Indian Scenario Absolute primary energy consumption is only 1/29 th of world, 1/7 th of USA, 1/1.6 th of Japan but 1.1 times that of Canada, 1.3 times that of France. 53% of the primary energy source available is coal.
Energy Star is an international standard for energy efficient consumer products. It was first created as a United States government program in 1992, but Australia, Canada, Japan, New Zealand, Taiwan and the European Union have also adopted the program
Star rating is a system initiated by BEE (Bureau of Energy Efficiency) to determine the energy efficiency of an appliance, like air-conditioners. Depending on their energy efficiency they are rated on a scale of 1 - 5 stars. Higher the number of stars, better is their energy efficiency.
The star rating system is a way of measuring energy efficiency. It’s applied to all electronic products such as Refrigerators, TVs , ACs and so on. Every AC model can get its EER tested and get a star rating. Currently, it’s voluntary, not mandatory for companies to get a star rating for their models.
