Green Heat - renewable energies for appropriate applications
How a range of renewable energies can provide space conditioning and water heating energy, and reduce more GHG emissions than all coal-fired generating plants.
Transcript

GreenHeat
‘heating and cooling
with renewable energies’
2013
Bill Eggertson, canadian association for renewable energies (we c.a.r.e.)
2.
3 applications for energy:
• electric power
• transport fuel
• heat • space heating
• water heating
• space cooling
3.
GreenHeat technologies:
1. biomass heat
2. solar thermal water
3. solar thermal air
4. earth energy (geothermal heat pump)
5. other

Residential (PJ)
2010 1990 % change
TOTAL 1,361 1,282 + 6
appliances 190 184 + 3
lighting 55 52 + 6
space cooling 27 10 + 156
water heating 238 220 + 8
space heating 852 817 + 4

ANCILLARY BENEFITS
• local content
• green employment
• displace fossils for other applications
• DR reduces grid congestion
• higher consumer comfort
• lower threats to occupant
• appropriate use of low-grade thermal
17.
SOLUTIONS
• greater awareness of therms
• baseline data
• more DG vs anti-LFE
• district heat / cool / DHW
• government procurement
• emissions credit
• GreenTherms Standard
18.
