Renewable Energy

Electricity from renewable energy in New Brunswick is increasing significantly. The government’s commitment is to increase the amount of electricity from new renewable sources in New Brunswick to 10% of total use by 2016. Currently, about 23% of the current electricity consumed in the province comes from renewables in the form of conventional hydro and wood. The development of wind power projects in the province has been accelerated and tidal energy is being examined more closely. In addition, the department continues to explore potential in biofuels and other clean energy sources.

Ocean Energy:

There are numerous types of energy possibilities that can be derived from the ocean. Wave and tidal energy, ocean current energy, offshore wind, salient gradient energy, and ocean thermal gradient energy are examples. Most of the current research and development in Canada concentrates on the wave and tidal current power generation.

What is Wave Energy?
As wind blows over the surface of the ocean, water is moved nearer to the surface and creates a wave. The energy that is available through waves depends primarily on a two factors, the length of the wave, and its height.

To capture the energy found in these waves and convert it to power there are numerous devices being developed. These devices typically fall into one of five categories:

1. Buoys
2. Surface Following
3. Oscillating Water Column
4. Terminators
5. Overtopping

What is Tidal Energy?
Tides are created by the gravitational forces of the sun and the moon. Tidal currents are the strongest where the water passes through narrow channels. In New Brunswick we are fortunate that The Bay of Fundy has the highest tides in the world. It is estimated that Canada's tidal energy potential could meet two thirds of our current demand.

There are three main types of technologies used to capture the tidal power and convert it to energy:

1. Vertical Axis Turbines
2. Horizontal Axis Turbines
3. Reciprocating Hydrofoils (operate much like a fish tail)

Wind Energy:

The province of New Brunswick has committed to increasing its generation capacity from renewable resources and as such has required, under the Electricity from Renewable Resources regulation, that NB Power purchase 10 per cent of it sales from new renewable sources by 2016.  The provincial government has accelerated this time frame by asking NB Power to move immediately with the addition of an extra 300 megawatts of wind power in New Brunswick, which would bring the wind power generation capacity to over 400 megawatts once all projects are completed. Electricity generation from wind is extremely important for New Brunswick, as it is a clean, sustainable and indigenous source of energy.

Solar Energy:

What is Solar energy:

Solar energy is a form of renewable energy which comes from the sun.  When the sun is shining we can harness the energy in order to create electricity and or heat.  One issue with solar technology is that it is still rather costly when compared to other renewables such as wind. Another is that it is weather dependant, it can only be used when the sun is shinning and therefore another energy resource would be required during times of cloud cover and or during times when the energy demand is high.

Solar energy can be used in various different ways:

Photovoltaic energy – Electricity is generated using solar panels which collect the suns energy through black panels which are coated in small solar cells.  When the sun shines on these panels, electricity is produced and feed into a battery or directly into the electrical system.  Solar panels can be placed on home, cottages, camper trailer and in many other places.  This technology is a good option for those who own camps or cottages in remote areas where you are not connected to the power grid.  Solar panels can also aid in reducing the amount of energy that you must purchase if you are connected to the electricity grid.

Thermal energy – Solar energy can also be used to produce heat.  Hot water can be produced by placing large black panels on the roof of your home and then passing water through them, this reduces the need to use electricity in order to heat the water in your home.  Solar energy can also be used to heat the air that circulates through a house or building.  These options reduce the need for electricity and as such can save you money down the road.

Biomass Energy:

This form of energy has no net greenhouse gas emission, since the carbon dioxide gases produced are recycled by plants, which absorb the carbon dioxide for photosynthesis and cellular respiration. This makes bioenergy an attractive, environmentally friendly, and sustainable alternative to traditional energy sources.

Bioenergy is not a new concept. It is one of the oldest of all energy resources, beginning with the controlled use of fire to provide heat, light and cooking for earliest mankind. The production of prepared biofuels also dates to ancient civilizations who made metal instruments in forges that burned wood in the form of charcoal. These civilizations also used liquid biofuels in the form of animal fats or vegetable oils for their lamps.

At one time in Canada, the combustion of biomass, usually wood, was the principal method for heating, cooking and providing hot water. Industry also used the combustion of biomass, along with water and wind power, as its principal source of energy.

Bioenergy includes solid biomass (i.e., forest product wastes, agricultural residues and wastes, and energy crops), biogas, liquid biofuels, and the organic component of industrial waste and municipal solid waste. Biomass-derived fuels are by-products of industrial or agricultural processes or fuels made from biomass feedstocks.

New Brunswick Biomass Development:

  • A Bio-Oil Development Centre pilot project is being undertaken by Greenway oils Inc in Waterville, Carleton County. Bio-Oil can be made from oil seed crops such as soya bean, mustard seed, and canola as well as other sources.
  • There are currently three facilities in New Brunswick which are using Bio-mass to produce electricity.
        • Fraser Paper (87.0MW)
        • Irving Pulp & Paper (30.0MW)
        • AV Cell Inc. (17.6MW)
Some of these facilities are cogeneration facilities where heat and electricity are produced and then reused during the manufacturing process.

Geothermal Energy:

Geothermal energy is the heat from the Earth. Resources of geothermal energy range from the shallow ground to hot water and hot rock, which is located a few miles below the Earth's surface, down further to the extremely high temperatures of molten rock.
