A simple problem with a simple solution. Global warming is fundamentally a very simple problem. Human use of fossil fuels — whether in the form of coal, oil or natural gas — releases carbon ...
Learn MoreHow do we solve the energy crisis in South Africa?
Learn MoreOther forms of alternative energy, including biofuels and hydrogen, have difficulties overcoming the most basic of problems: it takes more energy to produce them than the energy offered when consumed.. Another decent option is nuclear power, which is much more environmentally friendly than fossil fuels on a per-unit basis.However, waste …

Learn MoreSolar energy is key to solving climate change, but for the technology itself to be sustainable it needs to be recyclable. Unfortunately, when a solar panel dies today, it''s likely to meet one of ...
Learn More"Instead of trying to balance output at the panel level, the students looked to balance at the individual cell level," writes Sami Grover of The Huffington Post about a team of MIT students who developed an …
Learn More5. Solar Panel Problems. This is a common problem that most of the owners need to be careful of. One of the main causes of this issue is the broken glass of the solar panel. Damaged solar panels can cause solar collectors to be ineffective in catching the maximum solar energy.
Learn MoreWhen it comes to fixing common solar panel problems, a reliable clamp meter is a must-have tool for any solar energy enthusiast. A CAT III 1,500-V rated AC/DC clamp meter, like the Fluke 393 FC, can help measure DC power output from photovoltaic (PV) modules or arrays, as well as AC/DC voltage and current in electrical circuits …
Learn MoreFor solar, energy can obviously only be generated when the sun is shining – but people need power at any time. That gives rise to issues with storage and connectivity that are discussed below.
Learn MoreWave energy, which is one of the sustainable energy technologies are proposed to obtain useful energy from the oscillations (waves) caused by the air currents (wind) on the sea surface by the result of the low and high pressure zones caused by the temperature difference in nature, and the bottom currents which are the result of the …
Learn MoreIn this work, a flame-retardant and solar de-icing microcapsule material are prepared by using thermochromic materials as the core part, and melamine resin, phytic acid and chitosan as a double-shell structure. The as-prepared microcapsules were added to polyurea coating, thus solving the fire and icing hazards caused by the extreme weather.
Learn MoreFaced with connecting to a constrained grid suffering from frequent scheduled blackouts, known as load shedding, utility-scale solar PV in South Africa has had to have a degree of resiliency to it.
Learn MoreSolar''s current trends and forecasts look promising, with photovoltaic (PV) installations playing a major role in solving energy problems like carbon pollution and energy dependence. However, challenges related to solar energy threaten to slow …
Learn MoreFive ways to jump-start the renewable energy transition now
Learn Moretransmitted to the target ground wire through the hoop to break the ice on the ground wire. Two kinds of ground wire electric pulse de-icing device are shown in Fig. 6. The above two kinds of de-icing devices were tested. The number of turns of the arc loop coil of the arc-shaped device was 11, the flat coil of the flat-shaped device was
Learn MoreThe traditional method for anti-icing roads is distributing salt and sand. However, the method causes environmental pollution and damages to road infrastructures. A renewable alternative method for winter maintenance of roads is to use Hydronic Heating Pavement (HHP), coupled to a Ground Heat Exchanger (GHE). The aim of this paper is …
Learn MoreAlice Grundy explores the success of South Africa''s renewables auctions and the challenges that still remain for the development of PV in the country.
Learn MoreSolar energy is a powerful force of good. It has the potential to mitigate climate change, reduce air pollution, expand access to energy for all, and contribute to global economic well-being. The land use impacts of solar energy, however, are understudied. Research shows that by 2040 in the US, an area larger than Texas will be …
Learn MoreHow much solar energy is needed to melt all the ice? Assume that m ice = 10.0 kg. The heating source is the sun and we are trying to calculate the total solar energy. Put this on the left-hand side. The change that we want is the melting of the ice. We know the mass and the latent heat. We write those on the right-hand side.
