spent. "Even when the information is known and, despite the overall long-term cost-saving potential, the price of energy is too low...for individuals to justify the initial cost of energy efficiency measures." Not only are energy efficient devices more expensive, but "consumers are poorly informed about the savings on offer. Even when they can do the sums, the transaction costs are high: it is a time-consuming chore for someone to identify the best energy-saving equipment, buy it and get it installed." The technology used to measure the amount of energy that a consumer uses and saves, known as smart meters, grid systems, or energy dashboards, require time for the consumer to understand. Some argue that people need to have access to “simple yet effective information systems to help users understand their energy without having to become technology experts.” See also Energy and the environment Energy hierarchy Energy park Energy Star Environmental issues with energy Hydrogen economy International Renewable Energy Agency Leadership in Energy and Environmental Design (LEED) List of energy storage projects Renewable Energy Renewable Energy and Energy Efficiency Partnership Smart grid Sustainable Energy for All initiative References Works cited Airlie, C.
