Renewable energy can meet the world's power demands, and projections show it will supply nearly half of global electricity needs by 2030 and up to 90% by 2050. Achieving this requires significant investment, supportive policies, and a global commitment to energy efficiency to address challenges like the intermittent nature of sources like solar and wind.

Renewable energy can meet the world's power demands, and projections show it will supply nearly half of global electricity needs by 2030 and up to 90% by 2050. Achieving this requires significant investment, supportive policies, and a global commitment to energy efficiency to address challenges like the intermittent nature of sources like solar and wind. 
Projections for renewable energy growth
By 2030: -
Renewable energy is forecast to meet almost half of global electricity demand. Some estimates suggest it could be as high as 65%.
By 2050:-
 Renewables could provide about 90% of the world's electricity and 63% of total primary energy supply.
Specific milestones:-
Renewables are expected to overtake coal as the largest source of electricity generation globally by the end of 2025.

By 2026, wind and solar power generation are each projected to surpass nuclear power.
By 2029, solar PV is expected to become the largest single renewable power source, surpassing hydropower. 

Key factors and challenges
Growth drivers: -
Rapid cost reductions, especially for solar PV, and supportive government policies are driving growth.
Meeting demand growth: -
Renewables are already meeting the majority of the world's new electricity demand growth.
Energy efficiency: .-
To fully meet demand, a transition to renewables must be combined with significant improvements in energy efficiency.
System-level challenges: -
The intermittency of solar and wind power is a challenge that can be addressed through grid modernization, energy storage solutions, and a diverse mix of renewable sources.

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...
