  • However, the decline in the prices of clean energy technologies has reversed slightly in the past two years.
  • It is shown that the post-pandemic recovery has significantly propelled investments in the renewable energy sector.
  • It is found that annual investments in green energy have surpassed those in fossil fuels registering a growth of 24% against 15%.
  • Moreover, the instability in the fossil fuel market due to Russia’s invasion of Ukraine has accelerated the deployment of renewable energy technologies.
  • Renewable energy in EV and power is complemented by battery technology, heat pumps, and nuclear power.
  • It is estimated that in 2023, low-emission power will attract around 90% of the total investment in electricity generation.
    • Solar energy is projected to exceed $1 billion per day in 2023, totaling $380 billion for the year.
  • India has exhibited robust investment in solar energy.Β 
  • Brazil is also on a consistent upward trajectory. Investments are also increasing in West Asian countries like Saudi Arabia, the UAE, and Oman.

Associated Challenges:

  • The factors that are impeding investments in renewable energy are:
    • Higher interest rates
    • Ambiguous policies
    • Market designs
    • Financial constraints
    • High cost of capital
  • The prices of several crucial clean energy technologies experienced an increase in 2021 and 2022. This rise can be attributed to increasing input prices for critical minerals, semiconductors, and bulk materials like steel and cement.

  • A new Jupiter-sized exoplanet with the highest density of ~14 g/cm3 known to date has been discovered.
  • The new exoplanet discovered has a mass that is 13 times that of Jupiter.
  • This discovery was made using the indigenously developed PRL Advanced Radial-velocity Abu-sky Search spectrograph (PARAS) andΒ  PRL 1.2m telescope at Gurushikhar Observatory located in Mt. Abu.
  • The team of scientists involved in the discovery includes researchers from India, Germany, Switzerland and the US.Β 
  • The new exoplanet discovered was found around the star called TOI4603 or HD 245134.Β 
  • This newly discovered exoplanet β€œTOI 4603b” is regarded as one of the most massive and densest giant planets that orbits very close to its host star at a distance less than 1/10th the distance between our Sun and Earth.
  • This newly discovered planet falls into the transition mass range of massive giant planets and low-mass brown dwarfs.
    • Massive giant exoplanets are those having mass greater than four times that of Jupiter.
    • Low-mass brown dwarfs are those having mass equal to 13 times the mass of Jupiter.
  • The exoplanet with a surface temperature of 1670 K is said to be undergoing high-eccentricity tidal migration with an eccentricity value of approximately 0.3.
  • The discovery also marks the third exoplanet discovery by India, and by the PRL scientists using PARAS spectrograph and theΒ  PRL 1.2m telescope, following the discoveries of K2-236b (in 2018) and TOI-1789b (in 2021).
