Presentation by Paul Wallace of National Energy Action NI to the NICVA Centre for Economic Empowerment Masterclass on Energy Markets in Northern Ireland (17 October 2014). The presentation address the factors and implications of fuel poverty, what can be done to mitigate it, and the importance of energy efficiency.
3. Fuel Poverty Definition
โA household is in fuel poverty if, in order
to maintain an acceptable level of
temperature throughout the home, the
occupants would have to spend
more than 10% of their income on all
household fuel use.โ

effects on health
โข 18-24oC, no risk to healthy people
โข Below 160C, diminished resistance to
respiratory infections
โข Below 120C, increased blood pressure and
viscosity/strain on cardiovascular system
โข Below 90C, after 2 or more hours, deep body
temperature falls
โข Below 60C, place people at risk of
hypothermia (below โnormalโ core body
temp of between 36 โ 37.50C (96.8โ99.5ยฐF)

Getting the most from the energy we use
means using low energy lighting
100W bulb used for 1100hours* = 110 kWh
i.e. 110 units
110 units x 18.04p per unit = ยฃ19.84
*estimated annual use
20W CFL used for 1100 hours* = 22 kWh
i.e. 22 units
22 units x 18.04p per unit = ยฃ3.97
*estimated annual use
Thatโs a saving of over ยฃ15.00 per year!
Figures based on approx 3 hours use per day for 1 year

To this
Could save over ยฃ60.00 per year
(4 x ยฃ15.00)
20. LEDs โ more efficient.
More expensive to buy but save more
money in the long term.
Of course, the easiest way to save on your lighting bill is
simply to turn off the light when youโre not using it. You will
ALWAYS save energy if you turn the light off when you
leave the room, even if itโs only for a minute or two.

For appliances getting the most out of
the energy we use means replacing old
appliances with energy efficient models
and we have many more appliances in
our homes today than in the 1970sโฆ..

Energy Efficiency is also
keeping the heat where it is needed
for as long as possible
27. 27
According to the laws of heat
exchange, heat will always move
from a warm place to a colder area.
Thus a significant
amount of heat in the
home can be lost to a
colder outside
environment

Tutor instructions
Before showing the percentages ask delegates to identify what they think are the main areas of energy use in the home.
Ask delegates why there has been a growth in the amount of energy used by lighting and appliance since 1970.
Notes
The figures in the pie chart are from the Department of Energy and Climate Change (DECC) and are for 2011.Up until this point hot water was always second to space heating.
There has been a significant increase in the number of electrical appliances used in UK households since the 1970s. The Energy Saving Trust (EST) suggest that a typical household in the 1970s had around 17 electrical appliances, today it is approximately 45.
Delegates need to be aware of how energy is used within the home. Using efficient systems for space and water heating, improving insulation and changing behaviour regarding the use of electrical appliances can reduce the amount of energy consumed within the home and the cost of fuel bills.
Calculating running costs
60watt รท 1000 x 1000 hours = 60kWh x 17 pence = ยฃ10.20 over typical life of bulb
20watt รท 1000 x 10,000 hours = 200 kWh x 17 pence = ยฃ34.00 over typical life of bulb
9.5watt รท 1000 x 15,000 hours = 142.5 kWh x 17 pence = ยฃ24.22 over typical life of bulb
Energy saving/ Calculating comparisons
If a CFL is used rather than a traditional bulb the saving would be ยฃ74.01
CFL cost for 10,000 hours is ยฃ34 plus purchase price ยฃ3.99 = ยฃ37.99
60 watt รท 1000 x 10,000hours = 600 kWh x 17 pence = ยฃ102.00 plus price of 10 bulbs over 10,000 hours i.e. ยฃ102.00 + ยฃ10.00 = ยฃ112.00
Saving therefore is ยฃ112.00 โ ยฃ37.99 = ยฃ74.01
If a LED is used rather than a traditional bulb the saving would be ยฃ128.79
LED cost for 15,000 hours is ยฃ24.22 plus purchase price ยฃ14.99 = ยฃ39.21
60 watt รท 1000 x 15,000 hours = 900 kWh x 17 pence = ยฃ153.00 plus price if 15 bulbs over 15,000 hours i.e. ยฃ153.00 + ยฃ15.00 = ยฃ168.00
Saving therefore is ยฃ168.00 โ ยฃ39.21 = ยฃ128.79
According to the laws of heat exchange, heat will always move from a warm place to a colder area. Thus a significant amount of the heat in a house will be lost to a much cooler outside environment.
