This country is the focus of our presentation on electricity demand and emissions.

China

100

Short‑term visible air problem caused by coal combustion in cities.

Smog

100

Burning coal releases CO₂ and this gas that contributes to acid rain.

SO₂ (sulfur dioxide)

100

The new national measure described that guides China’s energy management.

Energy law (or new energy law)

100

Technology that moves large amounts of power long distances with low losses.

Ultra‑high‑voltage transmission (UHV)

200

The fuel that still supplies large shares of China’s electricity and raises CO₂ emissions.

Coal

200

Name one health risk linked to long‑term exposure to air pollution from coal.

Asthma, Heart Disease, Stroke, Lung Cancer

200

Term for heated water discharged from power plants that raises river temperatures

Thermal pollution

200

One main goal of the law: expand this type of energy to cut pollution.

Renewable energy

200

Storage technology used to shift midday solar to evening demand.

Batteries (battery storage)

300

Two renewable sources China is rapidly expanding

Solar and wind

300

Two social effects of large electricity systems (one positive, one negative).

Job creation; job loss in coal communities

300

Two ecosystem impacts of coal mining

Habitat destruction, water contamination

300

Two economic benefits of scaling clean energy manufacturing

Jobs, exports

300

One clear pro of long‑distance transmission for desert solar farms.

Delivers distant renewable energy to cities (reduces waste)

400

A reason electricity demand is rising: more of these vehicles are being adopted.

Electric cars

400

Why do power grids need many people and maintenance in big cities?

To prevent outages and keep the grid stable

400

Name one way coal plant waste harms water supplies.

Contaminates nearby water with mine runoff or plant waste

400

One short‑term risk if global demand for clean energy products slows.

Idle factories (or job losses)

400

Two cons of large transmission projects

High upfront cost, long construction timelines

500

Approximate annual CO₂ emissions mentioned in the script (in billion metric tons).

11.9 billion metric tons

500

Give one example of how coal‑related pollution can affect daily life in megacities.

Reduced visibility and breathing problems

500

List three habitat types commonly destroyed by coal mining

Forests, grasslands, rivers/streams

500

Name two system challenges caused by a fast shift to renewables

Grid upgrade costs, coal‑dependent job losses

500

Describe in one short sentence how storage + transmission + renewables work together.

They inecrease supply, move it where needed, and smooth variability to reduce coal us
