Green Technologies: Meaning, Types, Opportunities and Challenges | UPSC

 Understanding Green Technologies

  • Green technology is an umbrella term that describes the use of technology and science to create products and services that are environmentally friendly. Green tech is related to cleantech, which specifically refers to products or services that improve operational performance while also reducing costs, energy consumption, waste, or negative effects on the environment.
  • The goal of green tech is to protect the environment, repair damage done to the environment in the past, and conserve the Earth’s natural resources. Green tech has also become a burgeoning industry that has attracted enormous amounts of investment capital.

Types of Green Tech

  • Green technology is a broad category that encompasses several forms of environmental remediation. While climate change and carbon emissions are now considered among the most pressing global issues, there are also many efforts to address local environmental hazards. Some seek to protect specific ecosystems or endangered species. Others seek to conserve scarce natural resources by finding more sustainable alternatives.

a) Alternative Energy

  • In order to provide a viable alternative to fossil fuels, many businesses are seeking to engineer alternative sources of energy that do not generate atmospheric carbon. Solar and wind power are now among the most inexpensive sources of energy. Other alternatives, such as geothermal and tidal energy, have yet to be deployed at scale.

b) Electric Vehicles

  • Transportation activities are among the largest sources of greenhouse gas emissions. Many manufacturers are exploring ways to reduce automotive emissions, either by designing more fuel-efficient engines or shifting to electrical power.
  • However, electric vehicles require a host of innovations in other spheres, such as high-capacity rechargeable batteries and charging infrastructure. In addition, the benefits of electric vehicles are limited by the fact that many power grids still rely on fossil fuels.

c) Sustainable Agriculture

  • Farming and livestock have a substantial environmental footprint, from the high costs of land and water usage to the ecological consequences of pesticides, fertilizers, and animal waste. As a result, there are many opportunities for green technology in the area of agriculture. For example, organic farming techniques can reduce the damage due to soil exhaustion, innovations in cattle feed can reduce methane emissions, and meat substitutes can reduce the consumption of livestock.

d) Recycling

  • Recycling seeks to conserve scarce resources by reusing materials or finding sustainable substitutes. While plastic, glass, paper, and metal waste are the most familiar forms of recycling, more sophisticated operations can be used to recover expensive raw materials from e-waste or automobile parts.

e) Carbon Capture

  • Carbon capture refers to a group of experimental technologies that seek to remove and sequester greenhouse gases, either at the point of combustion or from the atmosphere. This technology has been heavily promoted by the fossil fuel industry, although it has yet to deliver on those expectations.

Advantages of green technologies

  • Green technologies offer numerous advantages across various sectors, promoting sustainability, efficiency, and economic growth. Some of the key advantages of green technologies are:

a) Environmental Benefits

  • Reduced Pollution: Green technologies help in reducing air, water, and soil pollution, e.g., electric vehicles (EVs) produce zero tailpipe emissions, significantly reducing air pollution compared to conventional gasoline-powered vehicles.
  • Lower Greenhouse Gas Emissions: They contribute to the reduction of greenhouse gas emissions, combating climate change, e.g., solar panels and wind turbines generate electricity without emitting CO2, unlike fossil fuel-based power plants.
  • Conservation of Resources: These technologies promote the efficient use of natural resources, reducing waste and conserving ecosystems, e.g., water-efficient irrigation systems, like drip irrigation, minimize water usage in agriculture, preserving water resources.

b) Economic Advantages

  • Cost Savings: Although initial investments may be high, green technologies often result in long-term cost savings, e.g., energy-efficient LED lighting uses less electricity and has a longer lifespan than traditional incandescent bulbs, reducing energy bills and replacement costs.
  • Job Creation: The green technology sector creates new job opportunities in manufacturing, installation, maintenance, and research, e.g., the renewable energy industry, particularly in wind and solar power, has created thousands of jobs worldwide in various capacities.
  • Market Competitiveness: Companies adopting green technologies can enhance their competitiveness by meeting consumer demand for sustainable products and practices, e.g., businesses implementing sustainable practices, like using biodegradable packaging, often attract environmentally conscious customers, boosting their market share.

c) Health and Social Benefits

  • Improved Public Health: By reducing pollution and harmful emissions, green technologies contribute to better public health outcomes, e.g., air quality improvements from the use of cleaner energy sources can decrease respiratory and cardiovascular diseases.
  • Enhanced Quality of Life: Sustainable technologies often improve the overall quality of life by providing cleaner air, water, and living conditions, e.g., green building practices, which incorporate energy-efficient designs and non-toxic materials, create healthier indoor environments for occupants.

Government schemes promoting green technologies in India

  • The Indian government has implemented several schemes and initiatives to promote green technologies. These include:
