- 7. # Green technology It means the technology which is environmentally friendly, developed and used in such a way so that it doesn’t disturb our environment and conserves natural resources. Unlike the technological waves in recent decades, green technology is almost entirely materials science based. Relying on the availability of alternative sources of energy. The purpose of this technology is to reduce global warming as ell as the green house effect. Its main objective is to find ways to create new technologies in such a way that they do not damage or deplete the planets natural resources. It also expresses less harm to human, animal, and plant health, as well as damage to the world, in general.

Environmentally friendly machines offer great solutions and encouraging developments in the high-tech sector. It’s about time everyone stood up and took notice of the abuzz in the world about the manmade rise of greenhouse gases. Eco-visionaries are already publishing data about the serious outcomes and encourage everybody to use environmentally friendly machines.

- 13. Enhanced Geothermal Systems The overall objective of Enhanced Geothermal Systems (EGS) is to harness the heat naturally generated by the Earth to produce electricity. In order to do so, wells are drilled into high temperature basement rock which is naturally fractured. The fracture network is enhanced to create a reservoir into which additional wells are drilled. Cold water is then pumped into the fracture network, via the wells, absorbing the heat of the rock as it passes through.

If we could collect all of that energy, we could easily power our homes and offices for free” Nano Solar managed to reduce production costs from $3 per watt to 30 cents per watt during the manufacturing of their Power Sheet cells. They managed this impressive cost reduction using an innovative technology which coats metal sheets, as thin as aluminum foil, with a microscopic layer of printer ink containing

Wave Power • ThePelamis is an offshore wave energy converter that uses the motion of waves to generate electricity. • The machine operates in water depths greater than 50m and is typically installed 2-10km from the coast. • The machine is rated at 750kW with a target capacity factor of 25-40 per cent, depending on the conditions at the chosen project site. On average one machine will provide sufficient power to meet the annual electricity demand of approximately 500 homes.

- 20. # Wind Energy Man has used wind energy for over 2000 years. In many places, wind energy was harnessed by windmills for pumping water and grinding grain. Windmills work by slowing down the speed of the wind. The wind flows over the blades causing them to turn. The blades are connected to a drive shaft that turns an electric generator to produce electricity. Wind turbines need a constant, average wind speed of about 14 miles per hour before the wind turbines can generate electricity. For

In our efforts to improve crop protection, commercial products, and medicines, we also caused unintended harm to our planet and humans. By the mid-20th century, some of the long-term negative effects of these advancements could not be ignored. Pollution choked many of the world’s waterways and acid rain deteriorated forest health. There were measurable holes in the earth’s ozone. Some chemicals in common use were suspected of causing or directly linked to human cancer and other adverse human and environmental health outcomes..

Green building(also known as green construction or sustainable building) refers to a structure and using process that is environmentally responsible and resource-efficient throughout a building's life-cycle: from siting to design, construction, operation, maintenance, renovation, and demolition. In other words, green building design involves finding the balance between homebuilding and the sustainable environment. This requires close cooperation of the design team, the architects, the engineers, and the client at all project stages. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green Buildings

It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce an environmentally-safe fluid waste stream and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm fertilizer). Sewage water treatment
