Variational method in the design of an optimum solar water heater storage tank [PDF]

open access: yes, 2006
Solar energy is a renewable resource because it is non-exhaustible and is available in abundance. The average daily total solar radiation amount in Malaysia is about 4500 Wh/m2, K.S Ong (1994).

Inter-annual variability of wind and solar electricity generation and capacity values in Texas

open access: yesEnvironmental Research Letters, 2019
As power systems shift towards increasing wind and solar electricity generation, inter-annual variability (IAV) of wind and solar resource and generation will pose increasing challenges to power system planning and operations.

Atlas of albedo and absorbed solar radiation derived from Nimbus 6 earth radiation budget data set, July 1975 to May 1978 [PDF]

open access: yes
An atlas of monthly mean global contour maps of albedo and absorbed solar radiation is presented. The atlas is based on 35 months of continuous measurements from July 1975 through May 1978.

Modeling Momentum-Diffusion in the Solar Wind [PDF]

open access: yes, 2018
The Sun is both a resource and a danger. We must be able to predict or have forewarning of large solar flares and coronal mass ejections (CMEs) and their potential threats to astronauts, GPS, radio communications, and power grids.

Parabolic trough solar collectors: A sustainable and efficient energy source

open access: yesMaterials Science for Energy Technologies
Fossil fuels are a finite resource that is becoming increasingly expensive. Solar energy is a renewable resource that has the potential to provide a lifetime supply of energy.

Learning-by-doing and the Costs of a Backstop for Energy Transition and Sustainability [PDF]

open access: yes
We assess the impact of being able to substitute an unlimited but costly energy substitute (like wind, solar) for a non-renewable resource (like oil, coal) in a model of sustainable growth.

Solar Resource Mapping of the Tigray Region, Ethiopia, Based on Satellite and Meteorological Data

open access: yesEnergies
The availability of properly analyzed energy resource potential data is a prerequisite in energy planning and development. However, this was sparsely applied in Ethiopia’s renewable energy turnkey project development strategies.

Interannual Variability and Seasonal Predictability of Wind and Solar Resources

open access: yesResources, 2017
Solar and wind resources available for power generation are subject to variability due to meteorological factors. Here, we use a new global climate reanalysis product, Version 2 of the NASA Modern-Era Retrospective Analysis for Research and Applications (
