Theme 2: Lesson 1

Explorer in action (Dr. Diego Ponce de Leon)

Dr. Diego Ponce de Leon:

• PhD from the Energy and Resources Group, University of

California Berkeley

He develops the use of technology to
Build renewable energy-related data infrastructure and systems these data allow him to:

• Collect data on power grids in order to improve the power system.

• Reduce energy waste.

Dr. Diego Ponce de Leon work help devices work efficiently by :
1. Connecting all the refrigerators and air conditioners together with a thermostat.
2. Programming a computer to monitor and control them.
3. He used sensors to monitor the appliances.
4. He used his knowledge of software to program the air conditioners and
refrigerators in a new, energy efficient way.

Thermostat a switch that measures temperature in air conditioners
and refrigerators.
Sensors devices which communicate information back to a
computer.
➢ The world has recently made a lot of progress in transitioning away from power
generated by fossil fuels. Instead, wind and solar power are being used.
Fossil fuels are derived from coal, natural gas, and oil.
He also used sensors to monitor
1. How much energy do the refrigerators and air conditioners used throughout the day.

2. By monitoring how much energy is being used Dr.Diego Ponce de Leon was able to
balance the power grid by moving and storing the electricity from one place to
another so that the amounts are more equal.
Example: How much electricity a town uses changes throughout the day. more energy
is used by air conditioners in the afternoon in summer because it is very hot out.
This way he could recommend ways to save electricity and build better energy

systems in the future.
