Asking the big energy questions How do we
Asking the big energy questions: ¡ ¡ How do we live sustainably on our planet? What tradeoffs must be considered if our society gets serious about making the transition from a consumptive society to a sustainable society?
A proposition: ¡ ¡ We NEED energy. The FORM of energy and the FUELS we use to create convenient energy are a matter of choice. (Electricity for buildings/Vehicles)
Write with your neighbor! ¡ ¡ Fossil Fuels Sustainable Energy What tradeoffs must be considered if our society gets serious about making the transition from a consumptive society to a sustainable society?
¡ So what will take the place of fossil fuels?
Every power system has pros and cons
Solar power must be stored for nights and cloudy days
Are we asking the wrong question? Should we be looking for a one-toone substitution solution?
Distributed power vs centralized power Creating a paradigm shift
Current electricity grid ¡ ¡ One major regional power plant, usually coal, natural gas or nuclear supplies area’s needs Same plan throughout US
Our electric “grid” = power plants connected to consumers
Our electric “grid” = power plants connected to consumers
A new energy concept ¡ Distributed Power = dispersed, small-scale power systems customized to geographic region combine to meet a region’s needs
The mix that works for Houston would be different than the mix for Detroit.
A Smarter grid – (how is it smarter? Compare to centralized)
Smart grid and smart meters ¡ ¡ Information allows for smart decision making Expected connectivity with major appliances
Decentralized power ¡ ¡ ¡ Advantages Greater reliance on renewables Decreased climate change Protection from centralized power outtages (storms, malfunction, terrorism) New jobs/new industries Promote more community ¡ ¡ ¡ Disadvantages Change is difficult Need for new infrastructure which may be costly Requires more cooperation Some jobs will be lost Shift in local economies
Sooooo. . . how would YOU put it all together? Fossil fuels climate change ¡ Demand for electricity and transportation ¡ Tradeoffs of all energy sources ¡ Growing population and affluence ¡ I=PAT ¡
