Answer 1

Technology is about adapting knowledge to specific requirements. Green technologies encompass various technological aspects that help us reduce the impact of humans on the environment and create ways for sustainable development. The main criteria for green technology include social justice, economic viability and sustainability. Today the world is racing towards the tipping point where we would have done irreversible lasting harm to the planet earth

Power generation is another field where green technology could bring wonders to light. Distributed generation technologies, e.g. solar photovoltaics, biogas processing, wind power, etc., have shown in practice that they can provide people with more job opportunities and can be implemented to effectively provide energy solutions to remote communities. Generation distributed in India holds much promise. Small-scale hydroelectric power and the photovoltaic sector have already achieved substantial participation in the private sector which is a big growth indicator.

There are live examples in India where people used alternative green power generation technologies and not only met their own energy needs but also sold their energy to the grid making substantial income. The same is true in countries such as Germany, where people sell electricity generated by their household Photovoltaic panels to the national grid and in rare cases may end up charging money from utility rather than paying. In this way, a person not only benefits himself or herself but also benefits the nation by actually contributing to the national power generation and thus proves to be an asset rather than an asset.

Eco-concrete is a green technology combining power, practicality and air-cleaning. It is designed to eat smog and pollution by converting oxide from nitrogen into harmless nitrogen compounds. These gasses have been shown to be decreased in the right conditions by up to 45 per cent. In Holland the concrete was already built and tested with positive results. The biggest problem with Eco-concrete comes from its cost-relative to regular concrete, because of the use of titanium dioxide it costs quite a bit more. Actually researchers are working to find a solution to the problem and to increase financial viability of the concrete.
