(5) A rural village with 10 000 residents depends on non-renewable energy sources such as paraffin lamps, wood, and coal for electricity and cooking. These practices have led to deforestation, health issues, and high energy costs. The village lacks modern infrastructure such as proper roads, schools, and healthcare facilities. A technology education team, including local leaders, is tasked with introducing renewable energy options (solar, wind, bioenergy) to improve living conditions while respecting cultural practices. Challenges include: reliance on tradition, high initial costs, potential design bias, sustainability of equipment, and integrating IKS with modern solutions. Answer the following based on the scenario: 4.1 Identify and analyse the social, cultural, and environmental challenges caused by dependence on non-renewable energy sources.

(5) 4.4 Examine the financial feasibility of installing renewable energy in the village. What funding models can be used? (5) 4.5 Propose a strategy led by the community to successfully implement renewable energy solutions. (5) A mountain-based settlement with 8000 residents lacks access to the national electricity grid. The community relies on diesel generators, causing noise, air pollution, and high fuel costs. The local council, in partnership with an engineering university, proposes installing micro-hydro systems from nearby rivers. However, they must overcome the following challenges: community resistance to change, a lack of technical skills, potential ecological disruption, cultural sensitivity regarding sacred water sources, and the long-term maintenance of the new systems. 4.1 Describe the cultural, environmental, and technical challenges of shifting from diesel to micro-hydro energy in the settlement.
