The conventional fuels are necessity for all the automobile machineries, due to deficiency of conventional energy sources need to search for alternative sources like biodiesels should give more impact to the automobile sectors. Biodiesel are clean energy, eco friendly, easily possible to produce from biomass. Alternative energy sources having more capable for solving environment aspects like reduce the pollution to the environment. This paper deals papaya seed oil used as feedstock, in this biodiesel produced by transesterification method using potassium hydroxide (KOH) as catalyst. This biofuel is used in four stoke, single cylinder, variable compression engine (VCR). The rated speed of the engine is 1500 rpm. This emission performance is analyzing for different nozzles with blends. Carbon mono oxide (CO) slightly increasing with load, Hydro carbon (HC) slightly decreasing with load, Carbon di-oxide(CO2) increasing with load. Oxygen (O2) is decreasing with load. Nitrogen oxide (NOX) and particulate matter is also increasing slightly with load.

With each passing year, the problem of using alternative energy sources is gaining increasing attention, since the energy of the sun, water and wind, unlike hydrocarbons, belongs to practically inexhaustible resources. Besides this, alternative energy sources are relatively environmentally friendly, so any country is interested in using them. One of the factors affecting the increase of energy generation from alternative sources is the legal regulation of this area by the government. In many foreign countries a number of conceptual, doctrinal and program documents are adopted and implemented, which are dealing with the use of renewable energy sources. In order to stimulate the use of alternative energy sources, the governments of some countries create favorable conditions for attracting investment in the development of this sector, which, further, not only creates new jobs, but also has a generally positive effect on the economy.

The study in this chapter examined policy options for promoting solar PV diffusion into the energy mix of six selected remote villages that were pilot sites for national and foreign assisted solar electrification programs in three ecological regions of Nigeria. A total of 910 questionnaires were administered on the solar PV users, suppliers, and government agencies to elicit information on alternative energy sources for provision of energy services. The results showed that solar PV usage was 49.9 kWh per/day, which constituted an insignificant share of about 14% in the total lighting requirement and less than 2% of the total requirement for energy services. The demand would rise to 73.3 kWh per/day by 2019 at the same 14% share of the total lighting requirement. Firewood demand maintained over 80 percent share (2383.5 kWh per/day) in the total energy mix in 2009. It also revealed that the best policy option of 200 percent increase in solar bulbs’ share for lighting by 2014 would require 50% reduction in kerosene share. The study concluded that increasing utilization of solar PV for lighting, entertainment, refrigeration, and ventilation in the study areas could lead to decrease in the use of energy from alternative sources.

In recent years, there have been strategy changes in international and European policies and procedures about the environment and sustainable development. The focus has been on the agents and activities that exhaust natural resources and harm the environment. The International Maritime Organization (IMO) and shipping companies' international organisations are trying to reduce the polluting emissions and greenhouse gases generated by vessels. This article looks at various alternative energy sources that can be used to power vessels and their auxiliary equipment, as well as at their economic and environmental repercussions on the transport of goods by sea.

This chapter discusses alternative energy sources and the advantages of biofuels over fossil fuels. It outlines the main steps of bioethanol production and suggests some alternative sources as potential feedstock. The core focus of this chapter is to examine new research which considers the use of agricultural waste as a feedstock for bioethanol production rather than conventional feedstocks such as sugarcane and corn. The advantages of sugarcane bagasse as a feedstock are discussed in detail and the bioprocessing requirements are studied in comparison to traditional methods that use sugarcane as the feedstock. The chapter concludes by briefly outlining further research that could potentially improve these processes.
