Apes In A Box Number 2
Notes
- Charcoal- Produced by burning wood to remove moisture.
- Advantages- higher energy content, easy portability, available in developing countries
- Disadvantages- deforestation, negative effect on respiratory system of producers and consumers
- Energy can be produced by burning garbage to produce steam for electricity
- Methane produced by bacteria decomposing waste can be harvested to generate electricity
- Garbage is readily available
- Advantages- domestic availability, cleaner burning that gas alone, infrastructure in place already
- Disadvantages- using food resources to produce fuel, lower energy content than gas alone
- Biodiesel- produced by removing oil from plants or algae. Mixed with diesel or burned directly in modified diesel engines
- Advantages- high net energy, lower CO and CO2 emissions
- Disadvantages- Land used for fuel instead of food, high land use, net energy dependent on type of crop
- Oil from algae- Algae is a promising source of oil
- It can be grown in tanks with little land disturbance, food prices not affected, CO2 from power plants and factories can be used to feed algae.
- Burning Solid Biomass- directly burning wood, plant materials, etc to produce heat, cook and use electricit
- Efficient and predictable energy source
- High net energy
- Downstream flood control
- Reservoirs can be used for recreation
- Reservoirs provide water for irrigation and municipal use
- Disadvantages
- Habitat destruction from creation of reservoir
- High initial construction cost
- Disruption of Fish Migration Routes by dams
- High CO2 production from decomposition of organic material flooded by reservoir
