Buildings and homes (or the ?built environment?) affects natural environment. Buildings, where people spend 90% of their time, adversely impact human health. Buildings also account for 40% of energy and 16% of the water used annually worldwide. Air quality inside buildings is 2 to 5 times worse than outside There are many factors to consider while studying the impacts of buildings Land use and ecosystems where buildings are built Materials and practices used to construct buildings Material, chemical, energy and water resources used to maintain ....etc

with the exception of hydroelectric power, most sources of renewable energy”solar, wind, and tidal power”have a pretty significant limitation: the energy source is variable. The sun isn't always up, the wind doesn't always blow, and the tides come and go, all of which leaves those running the energy grid with the challenge of evening out the power supply. Fortunately, this isn't actually a new problem, and there are many options being pursued for storing power from renewable sources.

Power companies have always faced the proble ....etc

Global Issues

Everyday radios, newspapers, televisions and the internet warn us of energy exhaustion, atmospheric pollution and hostile climatic conditions. After few hundred years of industrial development, we are facing these global problems while at the same time we maintain a high standard of living. The most important problem we are faced with is whether we should continue developing or die.

Coal, petroleum, natural gas, water and nuclear energy are the five main energy sources that have played important roles and h ....etc

The design, construction and maintenance of buildings has a tremendous impact on our environment and our natural resources. The buildings all together use the one-third of all the energy consumed in the country and two-thirds of all electricity. So the challenges is to build them smart, so that they use a minimum of nonrenewable energy, produce a minimum of pollution and costs a minimum of energy, while increasing the comfort, health and safety of the people who live and work in them. Here comes green buildings which alienates the isolation of ....etc

Introduction

According to the American Marketing Association, green marketing is the marketing of products that are presumed to be environmentally safe. Thus green marketing incorporates a broad range of activities, including product modification, changes to the production process, packaging changes, as well as modifying advertising. Yet defining green marketing is not a simple task where several meanings intersect and contradict each other; an example of this will be the existence of varying socia ....etc

Robert Green, an American Inventor, has developed a brand new technology which generates kinetic energy through the conversion of waste heat (as well as many other fuel sources). The Green Steam Engine is piston powered and designed for a wide assortment of practical applications. These steam engines are easy to build and can be used to power boats, electricity generators, air or water pumps, water distillers, heat pumps, air conditioners and a wide array of other small to medium sized appliances
