To what extent can advancements in space-based renewable energy technologies contribute to sustainable development and energy security on Earth?
Advancements in space-based renewable energy technologies have the potential to significantly bolster sustainable development and energy security on Earth. The core idea is to harness solar power in space, where the sun's energy is uninterrupted and more intense compared to terrestrial conditions. TRead more
Advancements in space-based renewable energy technologies have the potential to significantly bolster sustainable development and energy security on Earth. The core idea is to harness solar power in space, where the sun’s energy is uninterrupted and more intense compared to terrestrial conditions. This energy can be transmitted to Earth via microwaves or lasers, offering a constant and reliable power source.
One major advantage is the ability to provide continuous power, regardless of weather or time of day, addressing the intermittency issues of conventional solar and wind energy. This can enhance grid stability and reliability, crucial for supporting economic growth and development. Furthermore, space-based solar power (SBSP) can be scaled to meet large energy demands, making it a viable solution for energy-intensive industries and regions with limited access to terrestrial renewable resources.
Moreover, space-based renewable energy systems could help mitigate the impacts of climate change. By reducing dependence on fossil fuels and providing a cleaner energy source, SBSP can lower greenhouse gas emissions and contribute to global efforts to combat climate change. This aligns with the goals of sustainable development by promoting environmental stewardship and reducing the ecological footprint of energy production.
However, the technology is still in its nascent stages, with high costs and technical challenges such as the efficient transmission of energy and the construction and maintenance of space infrastructure. Significant investments in research and development are needed to overcome these hurdles. Despite these challenges, the potential benefits of space-based renewable energy make it a promising avenue for advancing sustainable growth and enhancing energy security on Earth.

Recently, the Cabinet Committee on Security approved the Indian Space Policy-2023, which has been formulated as an overarching, composite and dynamic framework to implement the reform vision related to opening up of the space sector for private participation. It can act as a catalyst for the development of a robust, innovative and globally competitive space ecosystem in India due to following reasons:
The Indian Space Policy 2023 sets the stage for a bold and ambitious future for India’s space sector, opening the door to innovation, collaboration, and international cooperation. However, it is essential to recognise that the global space landscape is not static but constantly evolving. India must embrace adaptability and strategic foresight to keep pace with these rapid changes.

A geomagnetic storm is a major disturbance of Earth’s magnetosphere that occurs when there is a very efficient exchange of energy from the solar wind into the space environment surrounding Earth. The largest storms that result from these conditions are associated with solar coronal mass ejections (CMEs) where a billion tons or so of plasma from the sun, with its embedded magnetic field, arrives at Earth.
Impact of geomagnetic storms Geomagnetic storms result in intense currents in the magnetosphere, changes in the radiation belts, and changes in the ionosphere, including heating the ionosphere and upper atmosphere region called the thermosphere. These geomagnetic storms are categorized between G1 and G5, the latter being the strongest. Their impact on the technology and infrastructure on earth includes:
Geomagnetic storms can also cause other phenomena. When solar matter collides with our planet at high speeds, the surrounding magnetic field deflects it towards the poles. There, it interacts with gases in the atmosphere, producing curtains of light known as auroras.
