Materials efficiency improvements from semiconductor applications
- solid state switches, relays instead of mechanical
- graphene for use in ultra-capacitors
- PV and organic PV over fossil fuel use
- OLED displays reduce need for backlight and are thinner over LCD
- quantum hall effect reduce B necessary
- Multi-functional materials - e.g. PV for building materials -- that can reduce overall building material use
- more advanced PV cuts material use in the PV but also the BOS
- PV replacement of batteries
- size reduction on electronics
- mutliuse devices -- see for example the long list of devices potentially eliminated with Hardware replaced by a smartphone
- remote energy savings - control furnace from airport
- thermostat controls
Energy efficiency improvements from semiconductor applications
- hybrid electric vehicles
- LED over both CFL and incandescent lighting
- photovoltaics
- more efficient inverters, DC/DC converters
- quantum hall effect reduces energy use in elecro-magnet
- reduced power usage in computers - via Quantum spin hall effect
- travel to stores - e-shopping
- travel for social interaction, education, work (telecommuting), banking, commerce, etc.
