 Introduction
Solar energy is the radiant light and heat from
the sun that can be harnessed and converted
into usable forms of energy, such as electricity or
heat, through advanced technologies. It is a
renewable, inexhaustible, and clean source of
energy that has the potential to significantly
reduce our dependence on fossil fuels.
Why Solar Energy?
1. Sustainability: Solar energy is abundant and will remain available as long as the
sun exists, unlike finite fossil fuels.
2. Environmental Benefits: It generates electricity without emitting greenhouse gases
or pollutants, making it an eco-friendly alternative.
3. Cost-Effectiveness: With advancements in technology, the cost of installing and
maintaining solar systems has significantly decreased.
Solar energy is at the forefront of the renewable energy movement and plays a crucial
role in combating climate change and fostering sustainable development.
 Global Energy Scenario and the Role of
Renewables
Environmental Concerns:
Burning fossil fuels emits greenhouse gases, contributing to climate change and global
warming.
Pollution from fossil fuel extraction and combustion has detrimental effects on air and
water quality.
Energy Security:
Many countries rely on energy imports, making them vulnerable to price fluctuations and
geopolitical tensions.
Finite reserves of fossil fuels raise concerns about long-term availability.
Energy Access:
Approximately 770 million people worldwide still lack access to electricity, highlighting
the need for equitable energy distribution.
