Which single technology in the list below can provide our society with a seamless transition to cheap, safe and carbon-free energy?

A)  Electric Cars

B)  Solar Power

C)  Hydrogen Fuel Cells

E)  Natural Gas

F)  Wind Turbines

This is a bit of a trick question, the answer is none of the above. There is no single "silver bullet" technology that will give us a simple transition to carbon-free energy for home heating, transportation, manufacturing and other large uses of energy. Every source of energy has its drawbacks and benefits, and a transition to new forms of energy will involve many different technologies, along with improvements in efficiency and changes in infrastructure.

A student at SEA recently asked the following question…

“What is the leading cause of preventable energy waste?”

Good question!

According to a study by the Lawrence Berkeley National Laboratory, home electronics such as TVs, DVD players, cable boxes, computers, game consoles (even when idle) and phone or electronic gadget chargers (especially when still plugged in and detached from the device) account for 5 % of the total of domestic energy consumption. If this equipment were plugged into power strips that were turned off when not in use, we could reduce our annual energy costs by more than $3 billion & carbon emissions by 18 million tons.

Wow, that is A LOT of preventable energy waste!
