resources needed to manufacture goods by efficient manufacturing processes and
decrease waste/pollution by efficient logistics as well as transport (Chandrappa and
Kulshrestha 2016).
Industrialization has both health costs and benefits. Proper planning, law,
enforcement and supporting infrastructure like common waste disposal facility is
required to dispose waste generated from an individual industry. In the absence of a
proper supporting infrastructure, manufacturers are likely to choose unhealthy practices to cut expenditure and increase profits.
9.6 Energy
Supply of energy is the main feature of the urban ecosystem. Energy use is essential
to human activity for preparing food, warming homes, producing goods besides
powering transport, among numerous other purposes (Kirk et  al. 2019). Except
solar energy, other forms of energy are imported to the urban ecosystem in the form
of electric power or fuel. Anthropogenic energy is coupled with pollution, ill health,
loss of ecosystem as well as climate change. The energy used in different parts of
world is not uniform and so is the impact.
Investment in clean energy is also an investment in public health. Smokey vehicles and coal- based power plants do harm the environment and the public, most of
which are irreversible. Dependence on fuel wood would lead to destruction of carbon sink beside emission of pollutants. Investment in clean energy resources like
solar, bio-fuel, wind energy and tidal energy can make a significant shift in the life
expectancy and health index of the community.
The history of human culture may be seen as the development of new energy
sources as well as their connected conversion technologies (Hill et al. 2003). The
control of fires for preparing food is the basic change that made humans different
from other animals (Wrangham 2010). Today’s energy sources vary from harvested/
scavenged biomass, animal power (dung, wood, peat), to commercial fossil fuels, to
processed biofuels as well as electricity (GEA 2012).
The utilization of fossil fuels has been a main element of the speedy social, technological as well as cultural changes and is integral to modern living. Energy security is also a growing concern to a number of governments and a source of
international conflict and tension (Paul et al. 2007).
The use of energy sources for human needs protects and enhances human health
in several ways. One of the reasons why poor people are less healthy compared to
rich people is due to a shortage of access to energy.
Poorer parts of the society have problems by paucity of affordable fuel due to
increasing energy prices, inefficient heating/cooling appliances and low thermal
insulation of the home. This fuel poverty has been aggravated by the sudden increase
in energy prices (Wilkinson et al. 2003; Healy 2003). Apart from these direct effects,
