The strengths and weaknesses of oil versus biomass are shown in Table 1.1.1.- Heating

Oil Biomass

Transport The oil wells are thousands of kilometers far from our highschool and the transport has a strong impact on our planet.

The source of biomass is the countryside of Baeza and the impact of transport is low.Win

Green house effect

The biomass is a renewable source of energy based on the photosynthesis carried out by trees and in this way there is a harmony between production and comsumption of CO2Biomass beats oil

Price The biomass is 50% cheaper than oil fuel

Storage safety

The storage of oil require strong measures of safetyLoose

There are no fumes at the storage room of biomass and no risk of explosion.In case of leak you can clean it with a broomWin

Volume required

for storage

Biomass requires double the amount of room for storage than oil

Maintennance

Win The biomass boiler needs a cleaning of the soot and ashes after a few days of use (2 to 10) while oil boiler needs maintenance only once a year.

1.4.- Conclusions

• The use of water spends huge amounts of electricity

• 41% of the production of electricity is obtained from the burning of

fossile fuels and 15% from nuclear fission

•Heating by fuel burning produces much more greenhouse effect than

heating by using biomass

•Greenhouse gases are the main cause of global warming, draughts and

extremely hot Summers like we had this year. No snow in Canada this

year until 20th of December!

WE NEED TO REDUCE THE USE OF OIL BURNING, ELECTRICITY AND

WATER

Below we will see some ways of approaching a more sustainable life and

cultivating better habits

Thank you notesI´d like to thank my coworkers in Highschool for all their supportI´d like to thank my students for their cooperation in leading highschool to sustainability

I´d like to thank Professor Deen at McMaster University without his support I wouldn´t be probably here talking to you
