Solution and Explanation
Step 1: Introduction to geothermal energy.
Geothermal energy is a renewable source of energy obtained from the natural heat present inside the Earth's interior. The word ``geothermal'' is derived from two Greek words: Geo meaning Earth and Therme meaning heat. Deep inside the Earth, rocks remain extremely hot due to radioactive decay and internal geological processes. This heat can be used to produce steam, which drives turbines to generate electricity. Since the Earth's internal heat is continuously produced, geothermal energy is regarded as a renewable and sustainable source of power.
Step 2: Continuous and reliable source of electricity.
Unlike solar and wind energy, geothermal energy is available throughout the day and throughout the year. It is not affected by weather conditions, seasons or daylight hours. Therefore, geothermal power plants can provide a continuous and stable supply of electricity, making them an excellent source of base-load power for industries, households and public services.
Step 3: Environment-friendly and sustainable.
Geothermal energy is considered an environmentally friendly source of power because it produces very low levels of greenhouse gas emissions during electricity generation. It reduces dependence on fossil fuels such as coal and petroleum, thereby helping to reduce air pollution and global warming. Since it is renewable, it contributes to sustainable development and conservation of exhaustible energy resources.
Step 4: Economic and developmental benefits.
Although the initial cost of establishing geothermal power plants is relatively high, operating and maintenance costs are comparatively low over the long term. Geothermal projects create employment opportunities, encourage technological development and provide reliable electricity for industries and nearby communities. In suitable regions, geothermal energy can also be used for space heating, greenhouse farming and tourism.
Step 5: Geothermal potential in India.
India possesses several regions with geothermal potential. Prominent geothermal sites include Puga Valley in Ladakh, Manikaran in Himachal Pradesh, Tattapani in Chhattisgarh, Cambay Basin in Gujarat and Bakreshwar in West Bengal. These regions have hot springs and geothermal reservoirs that can be scientifically developed for future electricity generation and other commercial uses.
Step 6: Challenges in the development of geothermal energy.
Despite its advantages, geothermal energy has certain limitations. Suitable geothermal reservoirs are found only in specific geological regions. The exploration and drilling process requires advanced technology and high initial investment. Continuous scientific monitoring is also necessary to ensure environmental safety and efficient resource utilization. However, with technological progress and government support, these challenges can gradually be overcome.
Step 7: Final conclusion.
Therefore, geothermal energy has immense potential as a renewable source of power because it provides clean, reliable and sustainable electricity with minimal environmental impact. By developing geothermal resources scientifically, India can diversify its energy mix, reduce dependence on fossil fuels and move towards a more sustainable energy future.
\[ \boxed{\text{Geothermal Energy is a clean, reliable and renewable source capable of supporting sustainable power generation.}} \] Geothermal energy has great potential as a renewable power source because it provides continuous electricity, produces very low pollution, reduces dependence on fossil fuels and supports sustainable development, although its development requires suitable geological conditions and advanced technology.

- Read the following source carefully and answer the questions that follow:
Print Comes to India
From 1780, James Augustus Hickey began to edit the Bengal Gazette, a weekly maga zine that described itself as ‘a commercial paper open to all, but influenced by none’. So it was private English enterprise, proud of its independence from colonial influence, that began English printing in India. Hickey published a lot of advertisements, including those that related to the import and sale of slaves. But he also published a lot of gossip about the Company’s senior officials in India. Enraged by this, Governor-General War ren Hastings persecuted Hickey, and encouraged the publication of officially sanctioned newspapers that could counter the flow of information that damaged the image of the colonial government. By the close of the eighteenth century, a number of newspapers and journals appeared in print. There were Indians, too, who began to publish Indian news papers. The first to appear was the weekly Bengal Gazette, brought out by Gangadhar Bhattacharya, who was close to Raja Rammohan Roy. - Read the following source carefully and answer the questions that follow:
Loans from Cooperatives
Besides banks, the other major source of cheap credit in rural areas are the cooperative societies (or cooperatives). Members of a cooperative pool their resources for coopera tion in certain areas. There are several types of cooperatives possible such as farmers cooperatives, weavers cooperatives, industrial workers cooperatives, etc. Krishak Coop erative functions in a village not very far away from Sonpur. It has 2300 farmers as members. It accepts deposits from its members. With these deposits as collateral, the Cooperative has obtained a large loan from the bank. These funds are used to provide loans to members. Once these loans are repaid, another round of lending can take place. Krishak Cooperative provides loans for the purchase of agricultural implements, loans for cultivation and agricultural trade, fishery loans, loans for construction of houses and for a variety of other expenses. - Arrange the following incidents in chronological order and choose the correct option.
