SURVEYS
ON ENERGY USE AND ENERGY EFFICIENCY
Surveys on
energy use and energy efficiency have been carried out in the hotel, industrial and SME sectors and services sector, with a view to
obtaining disaggregated date for, inter alia, planning purposes. Details on the
surveys and findings can be found hereunder.
HOTEL
SECTOR
A survey on energy use and energy efficiency
in hotels and hotels de charme was carried out in 2018 with the following
objectives: to determine the type and quantity of fuel being used, details on
different sources of electricity being employed and level of energy efficiency
of the hotel/hotel de charme as well as to obtain details on energy consuming
equipment.
The main findings of the survey are detailed
below:
1)
Electricity
represents 69% of the energy consumption of hotels, while LPG and diesel
represents 26% and 5% respectively;
2)
60%
and 30% of the hotels generate part or all their hot water from LPG and Diesel
respectively. Only 24% of the hotels have installed solar collectors for
domestic hot water production;
3)
Only
2 small hotels have installed solar PV for self-consumption and exportation to
grid;
4) The
main energy consuming equipment of hotels are air conditioning systems followed
by kitchen;
5) The
Energy Use Intensity calculated per meter square area and per room-night both
show that EUI increases with the star rating of the
hotel.

sector can be downloaded by clicking here.
INDUSTRY AND SME
SECTORS
A survey on energy use and energy efficiency
in the Industrial and SME Sectors, was conducted in 2018 with the main
objectives being, to obtain a breakdown of energy use in the industries and the
SME sectors and to determine the level of energy efficiency of the industry
facilities and SMEs, through Energy Use Intensity (EUI) calculations;
The main findings of the survey are detailed
below:
1) The
leading source of energy in 2015 for both Industrial and SME sectors was coal
followed by electricity but in 2016, electricity became the leading source of
energy;
2) The
leading end use of energy for the two sectors combined was internal steam
generation (ISG) during the three years followed by electric motors with 44.6%
and 19.9% respectively;
3) Only
5% of the firms use solar water heaters and only two firms have solar
photovoltaic installations;
4) The
Energy Use Intensity calculated per Production unit shows that the EUI for the
following subsectors were highest: manufacture of fabricated metal products,
food products and plastic injection molding.

and SME sectors can be downloaded by clicking here.
SERVICES
SECTOR
The services sector comprises several
subsectors, such as wholesale and retail trade, food services, ICT, Financial
and Insurance, Professional, Scientific and Technical, education, Human Health
and Social Work, Arts, Entertainment and Recreation. A survey on the energy use
and energy efficiency in the services sector was conducted with the following
objectives: to obtain a breakdown of energy use/energy consumption in the
Services sector, to obtain details on the renewable energy technology
installations and on stand-by generators installed in the sector and to
determine the level of energy efficiency of the Services sector, through Energy
Use Intensity (EUI) calculations.
The main findings of the survey are detailed
below:
1) Electricity
was found to be the leading source of energy at 55.7% followed by Gasoline which
is at 23.3%;
2) The
energy expense for the whole services sector was primarily Electricity at an
aggregated 93.8%;
3) Electricity
EUI per hour of operation is lowest for Food Services and highest for Storage at
3.5 kWh/hour of operation/year and 941.9 kWh/hour of operation/year
respectively;
4) The
Electricity energy use intensity per employee was highest for Storage followed
by Arts, Entertainment and Recreation.
