Abstract: Renewable energy supply has been very important and necessary in Tanzania due to recent high demand of energy supply, the high cost of supply of fossil fuels, and the increase of environmental impacts caused by frequently use of fossil fuel. At present Tanzania depends on hydro and thermal power supplies as the main sources of energy. On the other hand, many hydropower plants (sources) are mainly erected or placed in the existing natural flow of water in a given specific area, and therefore ensure the economical and viability of using the hydropower in that particular area. Practically, the high cost of transmission from hydro power sources prevent and hinder the grid connected electricity to the widespread populated area in Tanzania. The biomass use account for 89% of the energy consumption and it is estimated that, 90% of the population in the country relies on traditional biomass such as wood fuel and charcoal for cooking, because their majority are rural, poor and cannot afford the cost of modern energy sources such as electricity. The data shows that by 2015, about 24% of the total population in the country was connected to electricity, of which 11% is from rural areas. Only 12% of the hydro potential which is about 561MW has been delivered. The hydroelectric potential in the country is reported to be in excess of 4700MW of the installed capacity. Mini hydros have shown the potential of 187MW but only 4.7MW has been exploited. Tanzania has solar radiation of about 200Wp/m2, and the estimated potential of solar PV is around 20.2 MW. There are several sites with wind speed ranging from 5-7m/s mostly in central parts of the country. Co – generation and geothermal resources are estimated at 395MW and 5000MW respectively. However, still the utilization of these potential renewable energy resources remains very small especially in rural areas of the Country. Renewable energy resources, excluding large hydro has very little contribution in the generating capacity. This paper focuses on how renewable energy application based on local or decentralized grid on commercial bases will overcome energy deficiencies in rural areas of the country. The Government campaign on exploitation and use of renewable energy in rural areas will reduce rural poverty.

Abstract: The design of experimental rig for testing multipurpose blades was done to come up with a good blade that would be suitable for the pulverization of oil palm fronds and reduce toque, noise and vibration and fuel consumption during field operations. A good consideration on the strength of soil and fronds was done during the design. Mild steel was chosen for the frame design. From the design, work done to till the soil was found to be 34785.5Nm, diameter of the shaft was calculated to be 30mm, power transmitted by the belt and pulley is 104.4KN which falls between 20-150Kw and belt type D was selected. Belt length was 1,071.3mm which is within the standard length of 3127mm and belt D3127-IS: 2494 was selected. The electric motor to drive the blades carrier considering the power transmitted a 3Hp was selected and a gear motor to drive the experimental rig 4Hp was selected. It is expected that it would guide the manufacturers and stake holders in the oil palm industry to adopt better tractor mounted Mulcher for discarding oil palm fronds waste.
