To become a zero-carbon city, renewable energy must supersede other non-renewable energy sources and become the sole source of energy, so a zero-carbon city is a renewable-energy-economy city. Transitioning to a zero carbon city means examining the generation of power sources, such as renewable electricity and decarbonising electricity production.
The project was a short-term 2020 renewable energy strategy giving a 20% reduction in CO 2 emissions, ... Malacca has a stated ambition to become a carbon-free city ...
Renewable energy often displaces conventional fuels in four areas: electricity generation, hot water/space heating, transportation, and rural (off-grid) energy services. [22] Although almost all forms of renewable energy cause much fewer carbon emissions than fossil fuels, the term is not synonymous with low-carbon energy.
Renewable electricity generation by source and country in 2023 [1] This is a list of countries and dependencies by electricity generation from renewable sources. [1] Renewables accounted for 30% of electric generation in 2023. Renewables consist of hydro (47%), wind (26%), solar (18%), biomass (8%) and geothermal (1%).

The transition to a carbon-neutral economy will put more jobs at danger in regions with higher percentages of employment in carbon-intensive industries. [14] [15] [16] Employment opportunities by the green transition are associated with the use of renewable energy sources or building activity for infrastructure improvements and renovations. [17]
Moreover, the embodied energy and consequences of large-scale raw material extraction required for renewable energy systems and electric vehicle batteries is likely to represent its own complications – local emissions at the site of utilization are likely to be very small but life-cycle emissions can still be significant.
