Title: Energy system assessment and modeling of a potential future energy system on Lamu Island, Kenya
Authors: Dan-Eric, Archer
Abstract: The energy situation on Lamu today was mapped and visualized. Based on the predictions for future demand possible scenarios for energy sector was modeled and evaluated. The methodology shows a simplified picture of the energy sector and is based on many assumptions and mainly aim to show what possibilities there are for Lamu Island to become for self-sustainable in terms of energy. The current situation is that Lamu Island is very dependent on fossil fuels and woody biomass from outside the island for energy services, draining the local economy. A future Business-as-Usual scenario show how problems with current situation will increase if active measures are not taken. A ‘Light Green’ scenario demonstrates the effect of a few simple and easy actions are taken. The ‘Deep Green’ scenario predict what kind of investments and land use changes could be required in order to make Lamu Island energy self-sufficient. Other environmental threats was also investigated and it was found that the most urgent issue on Lamu is fresh and waste water system, which will soon have large economic effects if not addressed. The nature of the problem is investigated and possible solutions in term on increased rain water harvesting, reduced fresh water consumption and improved waste water treatment are investigated. Reducing the outtake from the Shella aquifer and better waste water management in Lamu town is required. Water, food, waste and energy are however interconnected systems why reduced fresh water use, better waste water treatment and energy efficiency improvements require combined solutions. These are reuse of waste water for irrigation and fertilization. Further it assist in removing use of firewood and charcoal in traditional stoves which is important for three reasons; health impacts, low energy efficiency and the global warming effect of the soot they emit. Energy sector governance of the Republic of Kenya is briefly analyzed and evaluated. Certain policies such as lack of grid feed-in with net charge system for households and design of the power producer Feed-in-Tariff system are inhibiting renewable energy investments and thus also sustainable development on Lamu. The goal is to provide material that will be useful for the governors and companies in order to take action and make decisions that will improve the energy, environment and economy future of Lamu Island.
