Solar and wind energy for the entire US state

12.04.2013

A new study shows that the US state of New York can be converted to alternative clean energy sources. What's more, the lead author of the large-scale study, Stanford Senior Research Fellow Mark Jacobson, is confident that it makes technical and economic sense.

It is hard to believe that this densely populated region of more than 19,5 million people and the famous giant city of New York can be provided with heat and electricity generated from wind, water and sunlight. However, calculations published in the Energy Policy show that this is quite realistic and will ensure a reliable supply of electricity. Moreover, it will be possible to create new jobs, improve the ecological situation and save billions of dollars.

The study by Jacobson and colleagues, the first of its kind, is the first plan to supply such a large developed region with energy exclusively from alternative sources. It includes everything: calculating the payback of infrastructure, the number of new generating devices, jobs, plots of land and ocean, the impact on mortality, morbidity, etc.

The researchers conclude that the transition of the entire New York state power system to alternative energy will initially require an increase in costs, but these costs will more than pay off by eliminating fuel costs. According to scientists, the demand for electricity in 2030 in New York State can be met with the following generation capacities: 4020 onshore and 12770 offshore 5-MW wind farms, 387 100-MW solar collectors, 828 50-MW photovoltaic power plants, 5 million 5 kW solar panels on residential rooftops, 500 100 kW solar panels on government and commercial rooftops, 36 100 MW geothermal heat sources, 1910 0,75 MW and 2600 1 MW tidal turbines, 7 1300- MW, hydroelectric power plants (most of which have already been built).

Together, these installations will completely cover the state's needs for electricity and heat for all sectors of the economy, including heating, industry and private households. At the same time, the number of deaths related to air pollution will decrease by 4000 cases per year, and the state will save about $ 33 billion (33% of state GDP) in health care. All new infrastructure will pay for itself in just 17 years.

Most of New York State's energy now comes from imported gas and coal. According to Jacobson's proposal, in the future, 40% of energy could be generated by wind, 38% by solar panels, and the rest by a combination of hydroelectric power, geothermal energy sources and tidal power plants.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

A simple way to extract uranium from seawater 17.10.2023

An international scientific team has presented a new, simple and effective method for extracting uranium from the waters of the World Ocean. The complex material used is highly selective towards uranium and does not interact with other molecules and metals in solution. This technology could be a promising alternative method for extracting a key component for nuclear power plants and treating nuclear reactor wastewater.

Uranium is an extremely valuable mineral that provides fuel for nuclear reactors around the world. In the oceans, the concentration of uranium is thousands of times higher than its reserves in the depths, but it is present in water in low concentrations (3,3 μg/l), which makes its extraction difficult. The main problem is the presence of other substances such as sodium, iron and calcium in much higher quantities in seawater.

Engineers used layered double hydroxides as the basis for their technology. This composite material is a layered structure with positively charged layers separated by negatively charged ions dissolved in water. These materials are already widely used to extract metals from liquids, are relatively simple to produce and can be easily modified.

To make the hydroxides selectively sensitive to uranium, the researchers introduced various lanthanide dopants such as neodymium, europium and terbium. Studies have shown that layered double hydroxides with the addition of neodymium interact with uranium 10 times more efficiently than with other metals dissolved in seawater.

The method also benefits from cost-effectiveness because the materials used in the process are fairly easy to produce and inexpensive, making them an attractive choice for large-scale uranium mining, according to Carolan Veliszek, one of the study's co-authors.
