Below are a few ideas on ways to reduce water usage in your office / workplace  Invest in water using appliances that have a five or six star rating.  Different water efficiency standard exist around the ...
... in thermal mass (e.g water tank, masonry wall) and slowly transmitted indirectly to the building through conduction and convection. Efficiency can suffer from slow response (thermal lag) and heat losses ...
Green building is the practice of increasing the efficiency with which buildings use resources — energy, water, and materials — while reducing building impacts on human health and the environment during ...
... at high temperatures (2300-2600 °C), but this process has been limited by complexity and low solar-to-hydrogen efficiency (1–2%). Another approach uses the heat from solar concentrators to drive the steam ...
... bottom. This solar pond was capable of producing temperatures of 90 °C in its bottom layer and had an estimated solar-to-electric efficiency of two percent.  Thermoelectric, or "thermovoltaic" devices ...
... along two axes. Parabolic dish systems give the highest efficiency among CSP technologies. The 50 kW Big Dish in Canberra, Australia is an example of this technology. A solar power tower uses an array ...
... and organizations that are direct consumers of energy may want to conserve energy in order to reduce energy costs and promote economic security. Industrial and commercial users may want to increase efficiency ...
Energy efficiency and renewable energy are said to be the “twin pillars” of a sustainable energy policy. Both strategies must be developed concurrently in order to stabilize and reduce carbon dioxide emissions ...
Using improved aerodynamics to minimize drag can increase vehicle fuel efficiency. Reducing vehicle weight can significantly also improve fuel economy. More advanced tires, with decreased tire to road ...
... of Energy, optimizing compressed air systems by installing variable speed drives, along with preventive maintenance to detect and fix air leaks, can improve energy efficiency 20 to 50 percent.  ...
