🌞 Renewable Energy
Part 1 of 7 — Solar, Wind, Hydro, and Other Renewables
Renewable Energy Sources
| Source | How It Works | Share of Global Electricity |
|---|---|---|
| Solar PV | Photovoltaic cells convert sunlight directly to electricity | ~4% (fastest growing) |
| Wind | Turbines convert kinetic energy of wind to electricity | ~7% |
| Hydroelectric | Falling water spins turbines in dams | ~16% (largest renewable source) |
| Biomass | Burning organic material (wood, crops, waste) | ~2% |
| Geothermal | Heat from Earth interior drives steam turbines | ~0.3% |
| Hydrogen fuel cells | + → electricity + | Emerging technology |
Solar Energy
| Type | Description | Application |
|---|---|---|
| Photovoltaic (PV) | Semiconductor cells convert sunlight to electricity | Rooftop panels, solar farms |
| Concentrated Solar Power (CSP) | Mirrors focus sunlight to heat fluid and drive turbines | Large desert installations |
| Passive solar | Building design that maximizes natural heating/lighting | South-facing windows, thermal mass |
🔑 Solar is now the cheapest source of new electricity in most of the world, with costs declining ~90% since 2010.
Concept Check 🎯
Wind Energy
| Pros | Cons |
|---|---|
| No emissions during operation | Intermittent (depends on wind) |
| Low operating costs | Bird and bat mortality |
| Small land footprint (base only) | Visual and noise concerns |
| Can coexist with farming | Not suitable everywhere |
Hydroelectric Energy
| Pros | Cons |
|---|---|
| No emissions during operation | Dams block fish migration (salmon) |
| Reliable, controllable output | Flooding displaces communities and ecosystems |
| Water storage for irrigation/flood control | Sediment trapped behind dam (downstream erosion) |
| Long lifespan (50+ years) | Methane from decomposing submerged vegetation |
Other Renewables
| Source | Pros | Cons |
|---|---|---|
| Geothermal | Reliable 24/7; very low emissions | Location-limited (volcanic/tectonic areas) |
| Biomass | Carbon-neutral if sustainably harvested; uses waste | Air pollution when burned; land use competition |
| Tidal/Wave | Predictable; enormous energy potential | Technology immature; marine ecosystem impacts |
Key Challenge: Intermittency and Storage
- Solar and wind are intermittent — they only generate when the sun shines or wind blows
- Solutions: battery storage, pumped hydro storage, grid interconnection, demand response
- Cost of lithium-ion batteries has dropped ~90% since 2010
Applied Recall ✍️
-
The renewable energy source that is the fastest growing globally is _______ photovoltaic.
-
A major environmental concern with hydroelectric dams is blocking _______ migration (especially salmon).
-
The main challenge with solar and wind energy is _______ — they only generate when conditions are right.
Match the Source 🔍
AP Exam Strategy: Renewable Energy
- Know the pros and cons of EACH renewable source — AP FRQs require discussing trade-offs
- Hydroelectric is the largest current renewable but has significant ecosystem impacts
- Solar and wind are intermittent — know the storage solutions (batteries, pumped hydro)
- Understand that "renewable" does not mean "zero impact" — all sources have trade-offs
- Geothermal is only feasible in geologically active areas (Iceland, western US)
- Hydrogen fuel cells produce only water as a byproduct — but hydrogen must be produced first
