Kristianstad Sweden Uses Biofuels Not Fossil Fuels for Heat and Electricity

Kristianstad Sweden uses no fossil fuels for heating.  Instead they uses biomass from farming leftovers.  80,000 homes heated by biomass and not fossil fuels like coal, oil and gas!  And this is an area of the world where it gets VERY COLD !

Since solar and wind would not be effective in Kristianstad they worked with biomass.  " ... remains from farming ... manure, potato peels, pig intestines, and even cookies, .... to create biogas  ... a certain type of  methane, ... heat of the entire city, and to provide electricity for the city as well."

The driving force for the move away from fossil fuels was to protect their environment and they did not want to import fossil fuels from abroad.

Sugar as Renewable Energy

Claren Power, a Arlington, Virginia company, " ... partners with sugar mills in Brazil to build modern, cogenerational ... facilities. The fuel comes from sugar cane waste—called bagasse... "

" ... using the waste product of the sugar after the stalks are crushed, ground and shredded and the juice is squeezed out. ... use ... as the fuel for our boiler, which heats water ... to generate steam. This pressurized steam drives a turbine, which is connected to a generator that converts this energy into electricity. ..."

"Most plants consume about a third of the energy (steam and electricity) that we generate during the harvest, leaving the other two-thirds to export to the electrical grid. Our goal is to help make plants more efficient so that we have more excess energy. We’re using the same resources but providing three times more energy."

GoodEnergy - Renewable Energy from Cow Poo

Good Energy, a UK supplier of 100% renewable energy, has the usual sources of renewable energy like solar and wind ... and green energy from cow poo.

Cow poo is turned into biomass and that in turn becomes biogas that is burned to become electricity ...

"Biogas is produced through ... Anaerobic Digestion ... a natural biological process carried out by bacteria in the absence of air, by which organic material is broken down into stable fertiliser and useful biogas. ..."

"The organic waste is broken down into sugars and amino acids by enzymes ... sugars are then fermented to produce volatile fatty acids and then converted by various types of bacteria into biogas, a mixture of carbon dioxide (40%) and methane (60%) ... "

" ... biogas is then ... burned ... to produce electricity and heat. ..."

Chicken Manure Powers 90,000 Homes in The Netherlands

Here is an interesting way to reduce waste. reuse waste and generate carbon neutral power from a virtually never ending supply of manure ...

" ... largest biomass power plant running exclusively on chicken manure has opened in the Netherlands ... will deliver renewable electricity to 90,000 households ... capacity of 36.5 megawatts ... more than 270 million kWh of electricity per year."

" ... more than merely “carbon neutral” ... manure ... spread out over farm land ... would release not only CO2, but also methane, a very potent greenhouse gas ... using the manure for power generation, the release of methane is avoided."

" ... plant will utilize approximately 440,000 tons of chicken manure, roughly one third of the total amount produced each year in the Netherlands. ... European countries ... suffer under an excess of different types of animal manure that pollute the environment."
