Three pillars of sustainability

Environmental, Social, and Economic pillars that support sustainable development.

Environmental pillar

Refers to the ability of natural systems to continue functioning without being depleted or degraded over time.

Social pillar

Refers to the ability of a society to meet the basic needs of its members while promoting fairness, inclusion, equity, and social justice.

Economic pillar

Refers to the ability of an economy to provide jobs, income, and resources for its citizens in a financially viable way.

Sustainability

Meeting the needs of the present without compromising the ability of future generations to meet their own needs.

Nuclear Power

Energy generated through the fission of uranium atoms, producing heat that is used to generate electricity.

Coal Power

Energy generated by burning coal to produce steam, which spins turbines to generate electricity.

Wind Energy

Energy produced by wind turning turbine blades to generate electricity.

Solar Energy

Energy produced by photovoltaic panels that convert sunlight into electricity.

Hydroelectric Power

Energy generated by flowing water turning turbines to produce electricity.

Gas Power

Energy generated by burning natural gas to produce electricity.

Renewable energy advantages

Lower greenhouse gas emissions, reduced air pollution, and helps to slow climate change.

Renewable energy limitations

Wind farms can affect wildlife, solar farms require large land areas, and hydroelectric projects can disrupt ecosystems.

Circular Economy

An economic system aimed at minimizing waste and making the most of resources by reusing, recycling, and refurbishing products.

Linear Economy

A traditional economic model characterized by the sequence of 'take, make, dispose.'

Transport equity

Ensuring all individuals have fair access to safe, affordable, and reliable transportation regardless of income or physical ability.

Urban Sprawl

The uncontrolled expansion of urban areas into the surrounding rural land.

Induced Demand

The phenomenon where increasing the supply of something, such as road space, encourages more people to use it, leading to congestion.

Phantom Traffic Jams

Traffic jams that occur without any apparent reason, caused by small disruptions creating a ripple effect.

Stroads

Streets designed as roads, aimed at moving vehicles quickly rather than accommodating community life.
