CLEAN ENERGY TECHNOLOGY EFFICIENCY AND MONITORING
DATE: TUESDAY, 29TH OCTOBER, 2013
VENUE: ADEYEMI BERO AUDITORIUM, IKEJA

2. What is Clean Energy Technology
Clean Energy Technology can be define as
creating Energy with smaller environmental footprint
and minimizing pollution.
Clean technology includes recycling, renewable energy
(WindPower, SolarPower, Biomass,
Hydropower, Biofuels), GreenTransportation,
Electric motors, lighting and many other appliances that
are now more energy efficient.

3. Clean Energy Technologies
 Recycling: is a process to change waste into new
products to prevent waste of potentially useful
materials, reduce the consumption of fresh raw
materials, reduces energy usage, reduce air pollution
and water pollution (from land filling)by reducing the
need for "conventional" waste disposal, and lower
greenhouse gas emission.
 Renewable Energy: Is defined as energy that comes
from resources which are continually replenished on a
human timescale such as Sunlight, Wind, Rain, Tides,
Waves

4. -Cont’d Green Transportation: This can be refer to when
transportation is sustainable which are largely being
measured by effectiveness and efficiency of any
transportation system as well as the environmental
impact of the system.
 Lighting: This is the use of both natural and artificial
light sources like lamps and light fixtures for
illumination by capturing daylight (using windows,
skylights, or light shelves) which are sometimes used
as the main source of light during daytime in buildings

7. Climate Change /Global Warming
 Climate change is a significant and lasting change in the
statistical distribution of weather patterns over time. It may be a
change in average weather conditions, or in the distribution of
weather around the average conditions (i.e., more or fewer
extreme weather events). Climate change is caused by factors
such as biotic processes, variations in solar radiation received by
Earth
 Global Warming is the rise in the average temperature of
Earth's atmosphere and oceans caused by increasing
concentration of greenhouse gases produced by human activities
such as burning of fossil fuel.

11. Energy Efficiency and Monitoring

Energy Efficiency is "using less energy
to provide the same service“
 For example : Replacing an incandescent lamp with a
compact fluorescent lamp (which uses much less
energy to produce the same amount of light) is energy
efficiency.

14. Energy Monitoring
 Hardware and software that connects to
your energy resources to provide a defined
baseline of energy consumption
 Knowing is the start – you need to see what
your energy usage is as a starting point
 However, Being green is not just a marketing strategy, it’s a
necessity to be efficient and reduce operating expenses

15. Energy Monitoring Technologies
 Three monitoring technologies
-Guessed/Estimated
-Current Measurement Only
-Power Measurement
 Guessed/Estimated- Good
-Not as accurate
The numbers produced by these guesses can be off by 20%
Really only works for lighting, not all loads

16. Current Measurement Only- Better
 -Mid-level accuracy
The works when we assume that the voltage is stable and
measure the actual current
P=I*V
 Can provide fairly accurate results for stable voltages
 Has a problem with active loads, like ballasts
 Power factor correction helps in the “on” state
 “Off” state will read much higher than actual power due to
phase shifts
 Can expect a 10% error in measurements
 Can be used for non-lighting loads

17. Power Measurement- Best
 Samples real voltage and real current at high
frequencies
 Compensates for phase offsets
 Doesn’t get fooled by voltage drops or non-linear
current scaling
 Expensive


Measured by a dedicated device: GLS-EM-MCU
Most accurate option for measurement
 Errors can be smaller than 1%
 Useful for measuring ANY electrical load

18. What are the steps involved
 Metering your energy consumption and collecting the data
by using an energy monitoring software
 Uncover places to save energy - such as making upgrades or
replacing inefficient equipment
 Putting into place energy saving functions – such as
demand response settings or eliminating wasted energy in
unoccupied spaces
 Tracking progress by analyzing the real-time data and
comparing with historical information to what these efforts
are actually achieving

19. Bringing it all together: Monitor, Manage AND
Control
