What is Renewable Energy?Derived from natural processes that are replenished constantly.Ressources

are replenished constantly.
Ressources exist over wide geographical areas.
Provides energy

in four important areas.

Слайд 7 Why Renewables?
Do not deplete natural resources.
Effective method

Why Renewables? Do not deplete natural resources.Effective method to reduce CO2

to reduce CO2 emissions.
Economic benefits
Reliable energy source
Guarantee energy security

for countries deploying it.
Legislation being passed making renewables more attractive.

Solar PowerGenerally captured in two forms. Remains an expensive method of

expensive method of generating electricity.
Advances in technology and

support from certain governments.

Слайд 11 Solar Power: Photovoltaic


Current is generated through Photovoltaic effect

Solar Power: PhotovoltaicCurrent is generated through Photovoltaic effect -flow of free

-flow of free electrons in Silicon Panel due to

solar irradiance

Direct current (DC) is generated which can be stored in a battery or converted to Alternating Current (AC)


Слайд 12 Solar Power: Solar Thermal
Sun’s infrared rays are concentrated

Solar Power: Solar ThermalSun’s infrared rays are concentrated through reflecting mirrors

through reflecting mirrors on a heating fluid (normally liquid

salt) medium, which in turn generates steam to propel turbines

Слайд 13 Pros and Cons – Solar

Environmentally friendly

Minimal maintenance

Maximum

Pros and Cons – Solar Environmentally friendlyMinimal maintenanceMaximum reliabilitySystems are easily

reliability

Systems are easily expanded




Most expensive form of energy
Produce

power only during day
Need large area for setup

Pollution level can influence sollar cells effectiveness











Слайд 14 Solar Photovoltaic Capacity and Additions

Solar Photovoltaic Capacity and Additions

Слайд 16 Wind Power
Converts kinetic energy of wind to

Wind Power Converts kinetic energy of wind to electrical energy.Renewable of

electrical energy.
Renewable of choice in Europe and the United

States.
Competitive alternative to more traditional methods of power generation.

Слайд 17 Wind Power

Wind Power

Слайд 18 Pros and Cons – Wind

Smaller Land requirement

Pros and Cons – Wind Smaller Land requirement when compared to

when compared to Solar, Hydro
Can be built off-shore

Cheaper than

Solar






The strength of the wind is not constant and it varies from zero to storm force
Wind turbines are noisy

Wind sites are often located in remote locations, so transmission lines must be built








Слайд 19 Wind Power Capacity and Additions

Wind Power Capacity and Additions

Слайд 21 Biofuels
Produced through contemporary biological processes, such as agriculture.
Ethanol

BiofuelsProduced through contemporary biological processes, such as agriculture.Ethanol is an alcohol

is an alcohol distilled from plant material (corn in

the U.S., sugar cane in Brazil, wheat in Europe) and used as gasoline substitute or blend stock.
Biodiesel is produced by the transformation of animal fat or vegetable oil into a conventional diesel substitute.



Слайд 22 Pros and Cons – Biofuels

Inherently renewable

Emit less

Pros and Cons – Biofuels Inherently renewableEmit less pollution than traditional

pollution than traditional petroleum based gasoline and diesel fuels

Easier

to transition to without special infrastructure needs





Not enough land space to grow crops for biofuel demand
Producing them actually requires more energy than they generate
Still polluting when compared to wind or solar








Слайд 23 The Bio-bean Start-up
Recycles waste coffee grounds into biomass

The Bio-bean Start-upRecycles waste coffee grounds into biomass fuel pellets and

fuel pellets and coals.
In the five-stage system, the grounds

are refined, agitated and dried out.
A 1 tonne pellet-bag is enough to heat a family home for a year.
Cheaper than wood pellets.

HydropowerPower derived from the energy of falling water or fast running waterLargest

fast running water
Largest global contributor amongst all renewable energies.
Most

mature of renewable energies

Слайд 27 Pros and Cons – Hydropower

The cheapest way

Pros and Cons – Hydropower The cheapest way to generate electricity

to generate electricity today.

The flow of water can be

controlled to produce electricity on demand.

Capable of large scale production.






Dams are extremely expensive to build.

Limited in number of potential sites/locations.

Flooding of land.
