The Need for Alternative Energy

Introduction / Meaning

Alternative Energy refers to the use of renewable energy sources such as solar, wind, and water as a substitute for non-renewable energy sources like crude oil and coal.
In the current global political scenario, dependence on oil has become highly risky.

Core Concept

1. Energy Security
The ability of a country to meet its energy needs reliably, affordably, and sustainably.

2. Geopolitics
Oil supply is controlled by political factors.
Example: Strait of Hormuz – handles about 20% of global oil trade.

Need for Alternative Energy

1. Geopolitical Risks
Iran conflict → rise in oil prices
1973 Oil Crisis → global economic impact
Russia–Ukraine war → gas crisis
Result: Price rise and inflation.

2. Import Dependency
Countries like India and China depend heavily on oil imports.
Result: Trade deficit.

3. Price Volatility
Oil prices fluctuate rapidly.
Result: Increase in transport cost, production cost, and inflation.

4. Environmental Impact
Coal and petroleum cause pollution.
Result: Climate change.

Features of Alternative Energy

Renewable – Solar and wind are inexhaustible resources.
Domestic Production – Reduces dependence on imports.
Decentralized – Can be produced on a small scale.

Global Examples

China – Increase in electric vehicles, reduced oil dependence.
Nepal – Growth in electric vehicles after the 2015 crisis.
Cuba – Increased use of solar panels.
Ukraine – Renewable electricity proved safer during war.

Impact

Advantages
Energy security
Control of inflation
Environmental protection
Long-term economic stability

Disadvantages
High initial investment
