WHY RENEWABLE ENERGY?

Enegy Consumption In World

SOLAR ENERGY

• The amount of potential solar energy is about twice as much as of all the non-renewableenergy resourcesin the world.

Advantages of Solar:

• Completely free after setup• No pollution• No need for maintenance• Long life spans• Easy to set up

Disadvantages of Solar:

• Expensive to invest in,• Dependant upon climate

WIND POWER

• In 2010 wind energy production was over 2.5% of total worldwide electricity usage, and growing rapidly at more than 25% per annum.

Advantages of Wind;

• Widely distributed• Uses little land• Produces no greenhouse gas emissions during

operation• Used for:a. Electricity productionb.Drainage and water pumpingc. Sailed ships

Disadvantages of Wind;

• Not pretty reasonable under most cases• Not constant• Expensive• Turbines are noisy• Produces pollution

TWEA

• Turkish Wind Energy Association increases public awareness about the significance of renewable energy resources, specifically wind.

Renewable Energy Resources Specific to Turkey

• Dung

• Nutshell

DUNG ENERGY• Traditionally cow dung has been used as a

fertilizer, though today dung is collected and used to produce biogas. This gas is rich in methane and is used mostly in rural areas as a renewable and stable energy source.

• Dung is a pretty common energy resource throughout Europe as it’s used in buses in Sweden which are named as “Dungbuses”

*BIOGAS

Energy Calculations

• Average energy consumption of an household

~ 3000 kWh/year (in Turkey)

• Average production of dung from a single cow

~ 600 000 kcal/year ~ 700 kWh/year

• Therefore approximately 4 cows can provide the energy needed for an house easily.

NUTSHELL ENERGY

• Turkey, often called as hazelnut land, each year produces almost up to 700 000 tonnes of hazelnuts which results in more than 400.000 tonnes of nutshell that is considered a waste product all over the world.

Advantages of Nutshell:

• Costs at least 50% less than others• Almost no pollution• Produces little ash• Amount of burning process is 99%• Can be used in heating due to ethol

Disadvantages of Nutshell:

• Storage takes a lot of space• Not consistent at all seasons

NUTSHELLS ARE USED:

• For heating,• For electricity,• Instead of charcoal in barbeques in the

most exclusive restaurants

COMPARISON

• Enegy & Cost Calculations

• 1.000 liters of Fuel-Oil : 10.000 KCAL ~ 880 €

• 1 tonne of COAL : 7.200 KCAL ~ 300 €

• 1 tonne of NUTSHELL : 5.500 KCAL = 130 €
