Twenty nine states have at least one commercial nuclear reactor. Most U.S. commercial nuclear power reactors are located east of the Mississippi River. Illinois has more reactors than any state (11 reactors at 6 plants), and at the end of 2019, it had the largest total nuclear net summer electricity generation capacity at about 11,582 megawatts (MW). The Grand Gulf Nuclear Station in Port Gibson, Mississippi, has the largest U.S. nuclear reactor with an electricity generating capacity of about 1,400 MW. The two smallest operating reactors, each with a net summer generating capacity of about 520 MW, are at the Prairie Island nuclear plant in Red Wing, Minnesota. Two new nuclear reactors are under construction in Georgia, each with a planned electricity generation capacity of about 1,100 MW. For cost and technical reasons, nuclear power plants are generally used more intensively than coal- or natural gas-fired power plants. In 2019, the nuclear share of total U.S. electricity generating capacity was 9%, while the nuclear share of total electricity generation was about 20%.
Markpointe understands, unlike fossil fuel-fired power plants, nuclear reactors do not produce air pollution or carbon dioxide while operating. However, the processes for mining and refining uranium ore and making reactor fuel all require large amounts of energy, and human energy. Nuclear power plants also have large amounts of metal and concrete, which require large amounts of energy to manufacture. If fossil fuels are used for mining and refining uranium ore, or if fossil fuels are used when constructing the nuclear power plant, then the emissions from burning those fuels could be associated with the electricity that nuclear power plants generate. Our team can support all aspects of the recruitment life cycle from qualified labor, radiologic technologist, to engineering.

Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants, and artificial photosynthesis. It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Markpointe contractor personnel are here to support all stages of projects from construction to maintenance.
Solar radiation is absorbed by the Earth’s land surface, oceans – which cover about 71% of the globe – and atmosphere. Warm air containing evaporated water from the oceans rises, causing atmospheric circulation or convection. When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth’s surface, completing the water cycle. The latent heat of water condensation amplifies convection, producing atmospheric phenomena such as wind, cyclones and anti-cyclones. Sunlight absorbed by the oceans and land masses keeps the surface at an average temperature of 14 °C. By photosynthesis, green plants convert solar energy into chemically stored energy, which produces food, wood and the biomass from which fossil fuels are derived
Active solar technology techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air.

Wind power has been used as long as humans have put sails into the wind. King Hammurabi’s Codex (reign 1792 – 1750 BC) already mentioned windmills for generating mechanical energy. Wind-powered machines used to grind grain and pump water, the windmill and wind pump, were developed in what is now Iran, Afghanistan, and Pakistan by the 9th century. Wind power was widely available and not confined to the banks of fast-flowing streams, or later, requiring sources of fuel. Wind-powered pumps drained the polders of the Netherlands, and in arid regions such as the American mid-west or the Australian outback, wind pumps provided water for livestock and steam engines.
Wind energy is the kinetic energy of air in motion, also called wind. Total wind energy flowing through an imaginary surface with area. The wind energy formula is given by, P = 1 / 2 ρ A V3. Where, P = power, ρ = air density, A = swept area of blades given by A = π r2 where r is the radius of the blades, V = velocity of the wind.

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit. These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.
Mining of stones and metal has been a human activity since pre-historic times. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed.
Mining operations usually create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the world’s nations have passed regulations to decrease the impact. Work safety has long been a concern as well, and modern practices have significantly improved safety in mines. No matter if you are searching for your next safety man, drilling operations director, heavy equipment operator, metallurgist, geophysicist, or engineer our team will support your operation.

In 1969, the United States enacted its federal Clean Air and Water Acts. Alberta did the same in 1971, as did many other Canadian jurisdictions, after pollution caught significant public attention during the 1960s. Shortly after, engineering consulting companies diversified and augmented their business with an environmental division. They started the service with internal expertise from the engineering disciplines of sanitary, geotechnical and water resource engineering. Early on, they recognized that non-engineering expertise was required. Hydrogeologists, soil, vegetation and atmospheric scientists were needed for the environmental impact sciences of groundwater contamination, mined land reclamation and air quality assessment. It was a frontier science back then, now it is best practice.
These legislative requirements have paved the way for the rapidly growing environmental service industry that has diversified to the point of no longer being a service that engineering companies excel in providing. Thousands of service companies now offer environmental assistance. The majority of cleanups typically involve removing waste from surface equipment (tank batteries, separators, etc.) and remediating affected soils at
abandoned well sites. Cleanup activities often follow well plugging activities. Funds are also used to cleanup abandoned pits, reclamation facilities and other types of sites such as abandoned natural gas processing plants, leaking pipelines, unidentified/illegal dumping of oil field waste, and emergency cleanups.
The adoption of worldwide environmental standards will expand international markets. Any privatization and deregulation of utilities such as water and electricity will expand the opportunities for foreign firms to participate. Consolidation of the industry and increasing firm size will also increase internationalization as we see today.

Batteries have been around for hundreds of years, and they’re going to be with us for some time to come. The many and varied applications for batteries has meant numerous permutations of the electrochemical cell over the years—different metals and other materials have been used for electrodes, different substances have been used for electrolytes, and there have been different ways of putting it all together. But what does the future hold?
The lithium-air technology is still a fair way from practical commercialization. Estimates are that it’ll take around 10–20 years for it to come to fruition. The developments described above work in a system that uses pure oxygen, so researchers also need to find a way to deal with the other stuff that air contains. Gases such as carbon dioxide and nitrogen in the air react with the lithium metal in the anode to form lithium carbonates and lithium nitrates which coat the electrode surface and prevent it from working effectively.
There are a few different materials that have been used for electrodes in sodium-ion batteries. Carbon is commonly used for the anode, but not in a neat arrangement of graphite as in a lithium-ion battery. When incorporated into a uniform structure, the large sodium ions get stuck and can’t get out again, making the cell reaction irreversible (and the battery unrechargeable). What’s needed to prevent this is the right pore size and distribution, and a high surface area—so ‘hard carbon’, generally made by burning sugars at high temperature, is used as the anode. The temperature is critical to getting the right properties.
A possible option is an anode made from layers of graphene interspersed with layers of phosphorene. The graphene provides elasticity and electrical conductivity to the electrode, and the phosphorene changes the structure of the electrode such that sodium can move in and out easily during recharge and discharge.
A number of different materials have been tried out as cathodes for sodium-ion batteries, but research is ongoing to find the best candidate. Recently, researchers found that a compound of sodium, iron and sulphate provided an excellent host for sodium ions. The material is formed of layers of sodium and iron interspersed with sulphate structures, which provides good spaces in which to house the sodium ions.
