Energy and Climate Policy – Lecture 10 Energy, Environment, Climate, and Human Health

Sample analytic questions

What are the environmental impacts of a fossil power plant?
How much water could you save if you replace all water cooling plants with air cooling?
What are the human health impacts of energy?
How climate change affect human health?
What are the co-benefits of energy transitions?

Energy system environmental and health impacts

System impacts
- Climate change
- Air pollution
- Health
- Water
- Land use
- Ecosystem

Example sources of energy related air pollution

Pollution by energy sector

Air pollution and human health analytic framework

Energy related PM emissions by sector and region

Air pollution standards (AQI)

Typical power plant emission control system

Pollution mitigation technologies and efficiencies

Outdoor air pollution and premature mortality

Trade, air pollution, and premature mortality

Energy sector accounts ~1/8 global water withdrawal

Water withdrawal vs. water consumption

Withdrawal is the volume of water removed from a source
Consumption is the volume of water withdrawn that is not returned to the source, i.e. it is evaporated or transported to another location.
Discharge is the volume of water withdrawn that is returned to the source, often degraded by use (altered physically or chemically) and impacting water quality.
Water withdrawals are, by definition, always greater than or equal to consumption and are, therefore, the first limit approached at an energy production facility when water availability is constrained.
Consumptive use reduces the amount of water available to satisfy demands downstream and is an important consideration where water resources are strained to meet the needs of all users.

Renewables save water

Dry cooling makes a big difference

Water-energy-carbon nexus

Land use intensity

Multiple uses of land, co-benefits!

NYC climate and health

Lancet countdown climate and health

Aging, climate, and health

Summary

Environmental, climate, and health impacts are the externalities of energy systems
Energy-air pollution/climate change-human health framework of analysis
Energy-water-carbon nexus
System impacts show the constraint in systems modeling
