in renewable energy (mainly wind
and sun) will also provide for excess
renewable electricity when the supply
supersedes the demand, which power
can be converted to heat and stored.
Next to this close proximity of heat
demand and supply South Holland
is also a densely populated region
with 3.6 million people (1,6 milion
households) living in an area of 2,818
km2. The majority of these houses
have been built before 1960 which
makes it more difficult to fully isolate.
There are also apartments in buildings
with 4 levels and above. This provides
South Holland with great economical
and technical possibilities for collective
heating systems.
With all the right conditions all-in
the same region: (1) being a densily
populated area and, (2) both a big
demand for heat and an abundance of
heat; a great possibility for a network
for heat comes up, named the heat
roundabout
FOCUS ON THE IMPORTANT ROLE
FOR INDUSTRY AND HEAT IN THE
TRANSITION
“No matter how many homes and
schools we help to become energy
neutral, nothing will structurally
improve if we do not focus on the
industries” – Arash Aazami
Most policies and subsidies in
the Netherlands focus on making
electricity in households sustainable.
A considerable effort goes into energy
efficiency measures (led lamps, and
energy saving appliance usage) and
the production of solar and wind
power to produce this electricity.
Only a small amount of effort goes
into measures for efficiency and more
green production for industry as well
as domestic heating. Considering that
household electricity consumption
accounts for only less than 2% of
energy use in South Holland, while
industry and heating account for
75%, this situation needs to be more
balanced.
