Sustainable Development & Green Technologies Flashcards

What is sustainable development?

Answer: Development that balances economic, social, and environmental factors.

Sustainable development is a holistic approach to progress that aims to meet the needs of the present without compromising the ability of future generations to meet their own needs. It integrates three interconnected pillars: economic prosperity, social equity, and environmental protection. This balance ensures long-term well-being for both people and the planet, promoting responsible resource use and inclusive growth.

What is the role of renewable energy in sustainable development?

Answer: To provide clean, sustainable alternatives to fossil fuels.

Renewable energy sources, such as solar, wind, hydro, and geothermal, are fundamental to sustainable development because they offer clean and inexhaustible alternatives to finite fossil fuels. By reducing reliance on fossil fuels, renewable energy significantly lowers greenhouse gas emissions, combats climate change, and improves air quality. This transition supports environmental protection while also fostering economic growth and energy security.

What is green technology?

Answer: Technologies that reduce environmental harm through innovation.

Green technology, also known as environmental technology or clean technology, encompasses innovations designed to minimize human impact on the environment. These technologies aim to reduce pollution, conserve natural resources, improve energy efficiency, and promote sustainable practices. Examples include renewable energy systems, waste treatment solutions, and sustainable transportation, all contributing to a healthier planet.

How do energy-efficient technologies contribute to sustainable development?

Answer: By reducing energy consumption and environmental impact.

Energy-efficient technologies are vital for sustainable development because they allow us to achieve the same level of service or output using less energy. This reduction in energy consumption directly translates to lower demand for fossil fuels, thereby decreasing greenhouse gas emissions and other pollutants. By minimizing environmental impact and conserving resources, these technologies support both ecological health and economic sustainability.

What is the purpose of green building practices?

Answer: To increase energy efficiency and sustainability.

Green building practices are designed to minimize the environmental footprint of buildings throughout their lifecycle, from design and construction to operation and demolition. Their primary purpose is to enhance energy efficiency through features like superior insulation and passive design, and to promote overall sustainability by using renewable materials, conserving water, and improving indoor air quality. This approach reduces resource consumption and environmental harm.

What is the role of water conservation in sustainable development?

Answer: To reduce water wastage and ensure long-term availability.

Water conservation is a critical component of sustainable development because fresh water is a finite and increasingly scarce resource. By reducing water wastage through efficient practices in agriculture, industry, and households, we can ensure its long-term availability for both human consumption and ecosystem health. This helps maintain ecological balance, supports economic activities, and prevents water stress in communities.

Why is waste management important for sustainable development?

Answer: To manage waste in an environmentally responsible manner.

Effective waste management is crucial for sustainable development as it addresses the environmental and health impacts of waste generation. By implementing strategies like reduction, reuse, recycling, and proper disposal, waste management minimizes pollution, conserves natural resources, and reduces greenhouse gas emissions from landfills. This approach helps create a cleaner environment and supports a more circular economy.

What is the concept of a circular economy?

Answer: An economy that focuses on reducing, reusing, and recycling materials.

A circular economy is an economic model that aims to eliminate waste and the continuous use of resources by keeping products and materials in use for as long as possible. Unlike a traditional linear economy (take-make-dispose), it emphasizes reducing consumption, reusing products, and recycling materials. This approach minimizes environmental impact, conserves resources, and fosters sustainable production and consumption patterns.

How do green technologies support carbon neutrality?

Answer: By reducing emissions and promoting the use of renewable energy.

Green technologies support carbon neutrality by directly reducing the release of greenhouse gases into the atmosphere. They achieve this through two main avenues: increasing energy efficiency to lower overall consumption and promoting the widespread adoption of renewable energy sources like solar and wind, which produce no carbon emissions during operation. This shift away from fossil fuels is fundamental to achieving a net-zero carbon footprint.
