Direct collection, conversion and storage of solar radiation as thermal energy are crucial to the efficient utilization of renewable solar energy and the reduction of global carbon footprint. This work reports a facile approach for rapid and efficient charging of thermal energy storage materials by the instant and intense photothermal effect of uniformly distributed plasmonic nanoparticles. Upo...

(c) (d) Photovoltaic solar cells tap into sunlight—the most abundant renewable energy source on the Earth—for electricity. Our planet receives ~1.2×1017 W of solar power, while the rate of current worldwide energy consumption is ~10,000 times smaller at ~1.3×1013 W.1 This means that the Earth receives more solar energy in an hour than the total energy it consumes in an entire year. Solar energy...

[1] The Mellor‐Yamada turbulence closure scheme, used in many ocean circulation models, is often blamed for overly high simulated surface temperature and overly low simulated subsurface temperature in summer due to insufficient vertical mixing. Surface waves can enhance turbulence kinetic energy and mixing of the upper ocean via wave breaking and nonbreaking‐wave‐turbulence interaction. The inf...

using hartree–fock (hf) and ِِdensity functional theory (dft) calculations the thermodynamic properties such as thermal energy , , thermal enthalpy , , thermal entropy , , thermal gibbs free energy , , heat capacity ,cv, and molecular structures of several species involving in keto↔enol tautomerism related to acetaldehyde (a), 5,5-dimethyl-1,3-cyclohexanedione (dimedone) and  acetylacetone (aa) h...

climatological study of the mid-latitude storm tracks was investigated using the daily global forecast system (gfs) and the national centers for environmental prediction (ncep) reanalysis data sets from 1948 to 2008 winter seasons. in anomalous winter 2007-2008, decreasing of eddy kinetic energy along with the reduction of eddy available potential energy upstream of atlantic storm track are rel...

Taiwan is eager to develop renewable energy because it is vulnerable to energy price distortion and ocean level rise. Previous studies show bioenergy technologies can be applied mutually, but pay little attention on feedstocks to energy conversion rate, which has potential influences on policy making in renewable energy and environment. This study employs a price endogenous mathematical program...

a detailed model of wind power station, including double fed induction generator, dfig is presented in this paper. two control mechanisms are included in the model. the inner control system uses stator flux oriented control for the rotor side converter and grid voltage vector control for the grid side converter. the outer control system is used for wind turbine pitch angle. pscad/emtdc is used ...

Ocean Thermal Energy Conversion (OTEC) relies on the thermal differences between ocean surface waters and cooler at c. 1000 m depth. The highest most reliable differentials are in low latitudes, 20° either side of equator, including Pacific Islands region. Whilst theory OTEC can utilize an inexhaustible amount stored energy within oceans, practice industry remains its technical infancy, but wit...
