  • Building Energy Modeling 101: HVAC Design and Operation Use Case

    A great deal of energy use in buildings goes toward heating, ventilation, and air-conditioning (HVAC). In 2015, HVAC consumed 15.5 quads. The first step in reducing HVAC energy use is reducing heating and cooling load—i.e., the amount of heat that needs to be added to or removed from a building—typically by reducing heat from equipment and lighting; minimizing unnecessary ...

  • Case study - Bank energy costs

    There are many pleasures of living and working in the Cayman Islands. However, paying utility bills for your business on Cayman isn’t one of them. The island territory has particularly high energy costs because Cayman has few domestic energy resources. Most electricity on Cayman is produced from imported diesel fuel, which is very expensive. As a result, businesses on Grand Cayman pay ...

  • Wind Energy Technologies: Technology, Market and Costs

    Technology Overview   These large wind turbines turn Midwestern wind into utility electricity. Wind turbines convert the power in the wind into electricity. By extracting the kinetic energy in the wind, wind turbines generate mechanical power. In the past, mechanical wind machines were widely used for specific tasks, such as pumping water or grinding grain. Today, wind ...

  • Energy cost for desalination evaporation versus reverse osmosis

    The selection of the appropriate desalination technology between evaporation and reverse osmosis is grounded on several factors, including investment cost, maintenance cost, degree of availability, heaviness of the duty, and the required purity of the desalinated water. The main factor is often the running cost of the plant, and specifically the cost of the consumed energy. This paper intends to ...

  • Solar Energy Costs and the Struggle for Grid Parity

    The price of manufacturing solar panels has dropped significantly in the past decade, and installation has risen as dramatically as prices have fallen. Yet the cost of solar energy varies from state to state and country to country, why? Even though solar panels are cheap to manufacture, the cost of financing, installing and maintaining a system add to the overall price of the product. ...

  • The importance of external costs for the competitiveness of renewable energies

    Low environmental damage is one of the main justifications for solar energy, especially now that supply security has slipped from public consciousness. In recent years, there has been much progress in the analysis of environmental damages, in particular thanks to the ExternE (external costs of energy) Project of the European Commission. This note presents a brief summary and comparison of ...
