  • How big is the distributed energy opportunity for water and wastewater utilities?

    Energy costs for water utilities are large, and growing Energy is a significant cost for many water utilities, and costs are growing as more energy-intensive forms of water supply, including desalination, are being used. Energy is typically the second-largest utility budget item in developed countries, after labour. In many developing countries, energy can account for 70% or even more, of ...

  • 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 ...

  • Solar hot water system

    Solar hot water systems (e.g. residential) do not produce steam, for example. Thus, solar hot water systems cannot push a steam turbine and will not generate electrical power. Solar hot water systems are used for heating and hot water requirements, not electrical power. If this is offsetting electrical hot water or electrical heat, then these are more like 'negawatts' than Terawatts. Steam ...

  • Solar Detoxification

    Introduction: In this process, vacuum extraction is used to remove contaminants from soils. After condensation, contaminants are mixed with a semiconductor catalyst such (e.g., titanium dioxide), and fed through a reactor which is illuminated by sunlight. Ultraviolet light activates the catalyst, which results in the formation of reactive chemicals known as 'radicals'. These radicals are ...

  • Tips for Solarization

    1-      In order to make plain use of sun energy during the application of solarisation, the cover should be cleaned if there is any dust over it. 2-      The area of application that will be treated should be processed up to 30-40 cm depth at first, the surface of ground should be balanced and rocks should be taken out. ...

  • Solar energy dissipation and temperature control by water and plants

    Ecosystems use solar energy for self-organisation and cool themselves by exporting entropy to the atmosphere as heat. These energy transformations are achieved through evapotranspiration, with plants as 'heat valves'. In this study, the dissipative process is demonstrated at sites in the Czech Republic and Belgium, using landscape temperature data from thermovision and satellite images. While ...

  • What Are Solar Buildings Technologies?

    Solar buildings technologies use the non-polluting power of the sun to help heat, cool, and power our buildings. Because buildings now use one-third of the energy currently consumed in this country, the potential markets for using solar buildings technologies in place of conventional ones is substantial. Whether you're a home owner, architect, builder, business owner, or industry or utility ...

  • A brighter future for solar in Texas

    I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that. - Thomas Edison, in conversation with Henry Ford and Harvey Firestone, 1931 According to the State Energy Conservation Office (SECO), Texas has the greatest solar energy potential of any state in the country. “If photovoltaic (PV) systems operating ...

  • Types of Solar Outdoor Lights

    Solar outdoor lights are slowly being taken up as a great alternative to grid lighting. This is actually a very good investment because it is very durable and provides good quality lighting for much less over time. It is also a green source of lighting since there are no emissions into the environment associated with solar lighting. Some people think that outdoor solar lighting is a ...
