Hydro

• Should you have an application for harnessing
  hydro energy. You are in great luck as this type
  of renewable energy is the most reliable,
  controllable and feasible installation. In
  addition it is most likely to have the shortest
  pay back period.
• A viable hydro application requires a minimum
  hydraulic head of 3 meters.

4
Geothermal / Heat Pump

• Geothermal refers to the heat that is trapped in
  the earth. In Ireland when people speak of
  geothermal heating they are often describing a
  broader concept of heat pump application. Heat
  pumps can be used to capture large quantities of
  low temperature heat and convert it into smaller
  quantities of higher temperature heat. This can
  be achieved anywhere heat is available. The main
  applications are from the Earth and ambient air
  or water sources.

5
Wind

• Ireland has an abundance of wind energy. Almost
  any location here will provide more energy than
  that of the best located sites in Europe.

• Utilizing energy from the wind remains our
  greatest obstacle.
• It is very expensive to store electrical energy.
• The way forward is to follow our European
  neighbours and adopt net metering.

6
Net Metering

• Net metering is achieved when the electricity
  created is synchronized with the national grid.
  It can then be connected directly to the grid
  called a grid tie installation. The electricity
  provider provides metering which can meter energy
  flow in both directions.

• When ample wind exists the system may export
  energy and conversely it will import in times of
  low wind. After an agreed period has elapsed the
  imported and exported figures are computed to
  determine the net import or export, each of which
  will be paid for at an agreed rate. This negates
  the need for storage.

7
Biomass

• BIOMASS is a very loose term in renewable energy
  context, but generally it means utilising the
  energy from organic materials, crops and by
  products such as chipped willow, grain, straw and
  palletised wood shavings etc. Principally
  speaking, 2.5 tons of biomass can substitute 1000
  liters of oil. Biomass may be even more
  attractive if you currently produce some of the
  above fuels.

8
Solar

• Solar energy is captured by every surface that
  the sun shines on. Some are more effective than
  others. Strong sunlight can deliver up to 1 kw of
  energy on each square meter surface area.

• Plants are by far the most efficient converters
  of solar energy. To date only two types of
  technology are broadly used in the capture of
  solar energy. These are solar water heaters and
  photovoltaic cells.

9
Solar water Heaters

• This is the most common application.
• It is primarily used to heat domestic hot water
  and can supplement approx 60 of total usage.
• The two main types are Flat plate and the more
  efficient (however not as aesthetically pleasing)
  Evacuative tube Solar panel.
• They have an unsubsidised payback period of
  approximately 16 years.

10
Photo Voltics

• This technology converts the suns rays into
  electrical Power
• PV systems currently cost approximately six euro
  per watt.
• In addition to this they require batteries and/or
  inverters to utilize their power.
• Their pay back is in excess of 20 years.

11
Hybrid Systems

• A hybrid system generally refers to a combination
  of two or more technologies.
• The most common referred to is the wind/ PV
  system which is configured to optimise energy
  production in varying weather conditions.
• These systems have a wind turbine and Solar PV
  feeding a common battery and or Inverter.

12
Anaerobic Digestion

• Natural gas is formed naturally by the
  decomposition of organic matter in an Anaerobic
  (oxygen free) atmosphere.
• Man has adopted and Improved this process for
  over 1000 years.
• Consequentially we know what conditions favour
  gas production and we simulate these conditions
  in a purpose built digester to produce and
  capture this gas.
• The decomposition of the matter in the digester
  is a form of waste treatment and reduces the risk
  to the environment.
