Increase in awareness about environmental protection is paving the way for research to identify various eco-friendly technologies. Most of these technologies do not hinder the luxury offered by the current technologies and at the same time they do not disturb the environment. A greater amount of pollutants are added to the environment by technologies that are used to produce electricity, heat and fuels that are used to power the automobiles. Thus by identifying the alternative, eco-friendly technologies for the above requirements would lessen the damage.

The following is a brief description of various eco-friendly technologies that are being used:
Simple products that we come across in our daily life like the fluorescent light bulbs, cars powered by bio-gas or alternative eco-friendly fuels, LCD monitors, construction materials are the few examples of by-products for years of research to save the environment.

As supposed, eco-friendly technologies are being identified to generate power and heating resources. Current available power generation technologies harness power out of natural resources like wind, hydro power, industrial or municipal wastes. To harvest wind power it is essential to have perfect planning and appropriate site selection. Other resources for power generation are biomass and waste. Most of the power recovered from biomass is utilized within the rural areas to pump water for irrigating agriculture lands and for industrial purposes. Making use of waste for power generation reduces the effect of these waster materials on environment in addition to generating considerable amount of power.

Solar energy is the most significant, abundant non-replenishing natural resource that can be used to generate power in various sectors like house-hold, small scale industries, agriculture products that are designed based on the solar energy include solar lanterns, home lighting systems, street lighting systems, solar water pumping systems, solar water heating systems, solar cookers, and solar air heating systems.

A great degree of investigation is being pursued to make use of various forms of energy like the hydrogen energy, geo-thermal energy, and tidal energy. Hydrogen having a great amount of energy per unit weight is used to power rockets. Research is being done to use hydrogen as a replacement to fossil fuels and to fuel vehicles. Geo-thermal energy that is highly available is being underused. Geothermal heat pumps can be used to heat buildings, to heat water that is used for various purposes like fish farming, and to drive turbines of power plants. Tidal energy with high energy is a potential source to generate electricity.

Eco-friendly technologies are being used in cultivating paddy crops. In addition to giving organic rice (grown without use of pesticides), it also gives good straw for cattle. As people prefer organic products, organic rice will have high demand and hence is economically beneficial. Investment costs are very less, thus attracting a great number of people.

Construction of eco-friendly roads is another progress towards protecting environment. This technology uses an additive of asphalt that has pores. By making use of this new technology the roads will be less slippery on rainy days due to their water absorption capacity and reduces the chances of forming ditches.

In addition to use of eco-friendly technologies to generate power and heat, recycling of waste and its minimization, recycling of various products should be given importance to have a green environment for years to come.
