‘Net-zero’ in the context of energy consumption refers to the concept of balancing the amount of energy consumed with the amount of renewable energy produced. Achieving net-zero means that any energy used must be offset by the same amount of energy generated from renewable sources or energy-saving measures. This balancing act is essential in mitigating climate change and minimizing environmental impact, as it leads to no overall increase in atmospheric greenhouse gases.

This approach encourages the use of sustainable energy strategies and technologies, ensuring that energy demands do not exceed the energy supplied through renewable means. This principle is crucial in discussions about sustainable development and energy policies aimed at reducing carbon footprints on a global scale.

The other options represent different aspects of energy and sustainability but do not accurately encapsulate the full meaning of 'net-zero.' Emissions reduction practices focus on decreasing greenhouse emissions without necessarily balancing energy production and consumption. Using only fossil fuel resources contradicts the net-zero concept, which emphasizes renewables. Minimal energy use in buildings addresses energy efficiency but does not reflect the overall balance between energy consumption and generation that characterizes net-zero objectives.
