Marine energy, or ocean energy, is a renewable power source harnessed from the natural movement of water—waves, tides, and currents—as well as ocean temperature and salinity gradients.

Marine energy, or ocean energy, is a renewable power source harnessed from the natural movement of water—waves, tides, and currents—as well as ocean temperature and salinity gradients. It offers a highly predictable and abundant, though still developing, alternative to fossil fuels with the potential to power homes, coastal communities, and the "blue economy"
.Key Aspects of Marine Energy:
Main Sources:-
 Wave energy (surface waves), tidal energy (gravitational pull), ocean currents, and Ocean Thermal Energy Conversion (OTEC).
Technologies: -
Devices include point absorbers (floating structures), oscillating water columns, tidal turbines, and barrages to convert kinetic energy into electricity.
Advantages:-
Predictability:-
 Tidal patterns are highly predictable, aiding in grid integration.
Abundance: ,-
Total available resources in the U.S. alone is equivalent to ~57% of U.S. power generation.
Sustainability: -
Low-carbon alternative to fossil fuels.
Applications: -
Powering remote, coastal, and island communities, as well as enabling offshore aquaculture, water desalination, and ocean observation.
Challenges: -
High initial capital costs, technical challenges in harsh, corrosive environments, and potential impacts on marine ecosystems. 
While offshore wind power is located at sea, it is technically distinct from marine energy. Research, such as that conducted by the NREL and Department of Energy (.gov), focuses on improving the efficiency and reducing the cost of these technologies. 
Marine energy -
Marine energy, also known as ocean energy, ocean power, or marine and hydrokinetic energy, refers to energy harnessed from waves, tides, salinity gradients.

Solar Generation in Night hrs

How to get get Solar generations in Night        While standard solar panels cannot generate electricity at night,     New technologies are being developed to address this limitation.      These advancements focus on harnessing the earth's heat or using infrared radiation emitted by the Earth to generate power, potentially creating 24-hour renewable energy sources.  Key Concepts and Technologies :- 1) Anti-Solar Panels (Thermo-radiative Cells):- How they work:-    These panels, also known as thermoradiative cells, work in reverse of traditional solar panels. Instead of absorbing sunlight, they emit infrared radiation into space, which is then converted into electricity.    Nighttime energy:-     They can generate electricity from the difference in temperature between the panel and the surrounding environment, essentially converting the heat escaping into space back into usable power.  Potential:-  ...

Hydrogen at home — It's the end of solar and wind power

  Hydrogen at home — It's the end of solar and wind power         Statement "1000 pounds" per day of hydrogen at home — It's the end of solar and wind power in the world" is not accurate.     While hydrogen can be produced from renewable energy sources like solar and wind power, it's not a replacement for those sources themselves. Hydrogen production via electrolysis, using renewable electricity, is a promising avenue for decarbonization, but it doesn't negate the need for solar and wind power as direct energy sources.  Cause behind its is as under. Hydrogen as an Energy Carrier:-     Hydrogen is an energy carrier, meaning it stores energy produced elsewhere (like from solar or wind) and can be used to power fuel cells or for other applications.  Electrolysis:-     A key method of producing "green" hydrogen involves using electricity from renewable sources (like solar and wind) to split water into hydrogen and oxygen throu...

State-wise carbon emissions in India show a concentration in western and southern states, with byd as major emitters, particularly from the manufacturing and energy sectors. The highest total CO2 emissions have been linked to states like Maharashtra, Andhra Pradesh, Uttar Pradesh, Gujarat, Tamil Nadu, and West Bengal, though the specific ranking can vary depending on the data year and the specific pollutants included.
