Top Oil & Gas Companies

Changing conditions and volatile markets have made it difficult to follow trends among oil and gas companies. Advancements in renewable energy sources, much of the world remains dependent on petroleum for their everyday needs. This compilation of the top oil and gas companies reflects the stable and growing economy that is petroleum.


One of the oldest American petroleum companies, Chevron was founded in 1879 in a then remote area of California. Today, Chevron Corporation operates in nearly 200 countries and boasts a market value of about $227 billion and a current share price of more than $120.

Exxon Mobile

The $295 billion market value, it would appear that Exxon’s spotty history has been all but forgotten by the public. The popular brands merged in 1999 and quickly began rising to the top. The current stock price of around $70 confirms that a healthy recovery is likely underway.

China National Petroleum Company

Since 1988, the CNPC has been making headlines from its Beijing headquarters. Not only is this conglomerate one of the largest oil and gas companies in the nation, it is one of the biggest corporations in the world. Fortune Global 500 ranked them among the largest companies by revenue in 2017 and 2018.

Abu Dhabi National Oil Company

Founded in 1971, this state-owned petroleum company has steadily increased in revenue and global exposure. The United Arab Emirates company claims access to the 7th largest oil reserve in the world. The average daily production is around three million barrels per day. Excellent management and efficient processes account for the rapid success of this international company.


Arising as a result of a merger between Conoco Inc and Phillips Petroleum Company, this Houston, Texas-based company has proven that it has the endurance for long term success. With an annual revenue of around $40 billion and a stable stock share price hovering $65, ConocoPhillips does not fall among the largest oil and gas companies. However, this little giant offers local and international perks like community involvement and environmental awareness.

Companies that specialize in the production or transportation of oil and gas face uncertainty. Investors are cautioned to remember that energy companies can move from the top of the list without warning.

How Can AI Impact Renewable Energy

Artificial Intelligence (AI) technology has quickly made its way through various industries and businesses. New technological developments have changed the way many processes are completed, and when it comes to AI, the possibilities seem endless. AI technology uses data and advanced algorithms to think, calculate, analyze, and predict information systematically. The idea is to mimic that of a human brain (with a little extra brainpower). In the energy industry, artificial intelligence plays three primary roles:

Energy Forecasting 

Weather forecasting isn’t only a large part of meteorology. In the energy industry, weather forecasting is essential. AI algorithms use industry data to make accurate weather forecasts that will impact renewable energy sources like solar or wind power. Because these power sources are highly based on the weather, they tend to fluctuate, making it more difficult to balance supply and demand. Tech companies use data mining to pool data from the industry with weather forecasts to make accurate predictions. 

Energy Efficiency 

Aside from using AI for weather forecasting, companies like Google have acquired AI applications like Deepmind, to improve the use of energy. After Google’s acquisition of Deepmind, the AI application reported a 40% reduction in the amount of energy it took to cool Google’s data centers. Deepmind’s AI technology was used to train a system of neural networks in the data centers. The neural network then learned the function of the data center and started to identify areas for improvement and optimization. 

Energy Accessibility

For accessibility purposes, AI is used to model potential savings costs on utilities using energy industry data, mainly in the smart home sector. For example, energy-conscious homeowners can use AI applications to assist with energy management within their homes. Homeowners can see collected data recording how much energy their home appliances use, thus assisting in monitoring monthly utility costs. 

The future of artificial intelligence in the energy industry is likely going to increase as businesses and homeowners seek the ability to make more accurate predictions and save on energy costs.

The Positive Impact of Renewable Energy

Energy is a necessary need for every human being on Earth. Harvesting and utilizing natural resources is a vital part of survival for both individuals and societies. As technology advances, how energy is collected has also become more efficient. Unfortunately, many energy providers still rely on antiquated resources such as coal, wood, and natural gas. These types of natural resources can no longer satisfy the massive energy needs of an increasing global population–at least not without an expensive and harmful impact on the environment.

Many people are familiar with solar, wind, and hydroelectric sources of power; however, innovations in hydrokinetics, biomass, and other forms of sustainable energy have bolstered the number of alternatives to non-renewable energy. 

There’s no way to eliminate the environmental impact of harvesting energy, but the process of extracting energy from these cleaner sources releases minuscule carbon emissions compared to classic energy plants.

Beyond considering the future of the planet, there is also an immediate economic benefit to renewable energy. Construction and maintenance of renewable energy plants are much less costly than their non-renewable equivalent. More labor is also needed, leading to increased job opportunities. Finally, public health has been impacted by the adverse effects of non-renewable energy, causing the healthcare sector to bleed money from national wealth.

Coal, oil, and gas are being used at a much faster rate than they can naturally form, leading to their inevitable exhaustion in the future. The disastrous effects of non-renewable energy are self-instigating. As carbon gasses take their toll on the availability of clean air and water, as well as raising the global temperature, natural disasters are becoming more of a risk. Events such as droughts and heatwaves have terrible effects on non-renewable power plants. On the other hand, wind farms can work in a modular system that mitigates the impact of destructive situations.

Leaders around the world have already committed to increasing the use of renewable energy, yet there is still much progress needed to protect ourselves and our environment. At one point, whale oil was the preferred energy source for keeping a light on at night; now, it’s time for humanity to look towards a cleaner and safer solution to meeting energy demands.

Pros and Cons of Hydropower

Renewable energy sources have been on the rise as home, and business owners become more environmentally conscious. Hydropower, specifically, is the most widely used source of renewable energy. According to the USGS, hydropower represents about 17% of total electricity production. Hydropower plants utilize running water stored in dams or naturally flowing rivers to create electricity. The water rotates turbine blades that spin a generator to convert mechanical energy into electrical energy. While hydropower is a great way to minimize air and water pollution, like many other forms of renewable energy, there are pros and cons. 


Minimal Pollution 

One of the most significant advantages of hydropower as an energy source is its minimal pollution level. Since hydropower is fueled by water, it’s a clean form of fuel; meaning, the plants won’t pollute the air like other power plants that produce energy using fossil fuels like natural gasses or coal. 

Low Operation and Maintenance Costs 

Hydropower plants have much lower operating costs than other energy-generating plants that use fossil fuels. River water is a constant resource, so any volatility in the economy doesn’t cause an impact. Fossil fuels, on the other hand, are primarily impacted by economic fluctuations, causing their prices to quickly fluctuate with any changes in the market. 


Because hydropower generates energy through the water cycle and the sun, it is considered a renewable energy source. This works hand in hand with the low market costs to make hydropower a reliable and affordable energy source.   


High Investment 

Although hydropower is a reliable energy source with low operation and maintenance costs, initial investment costs for hydropower plants can be high. “Hydroelectric power plants are very costly to construct due to logistical challenges like topography, laying foundations underwater, and the materials used to build it. The only upside is that after completion, it will require less maintenance.”

Negative Impact on Aquatic Habitat

With the potential for environmental benefits, hydropower can also cause some environmental damage, especially when it comes to aquatic life. Building dams for the plants can impact the breeding season for fish, as well as create an unfortunate food shortage, ultimately leading to a drop in reproduction rates and a rise in overall death for various species of fish.

How New Technology is Improving the U.S. Power Grid

How New Technology is Improving the U.S. Power Grid _ Blake Zimmerman Houston

In the United States, the essence of electric connection and the vital role it plays in facilitating economic growth and development cannot be overstated. Unfortunately, the national power grid system does occasionally face significant failures because of overloading and other systemic errors. Technology has solutions to offer as far as helping maintain the integrity of the power grid system is concerned.

Engineers who did the national power grid system for the country never designed it to undergo some of the grueling overloads it faces today. Currently aged over 25 years, the system was engineered to last only 30 years.

Blockchain technology, however, can help much in ensuring that our existing power grid system serves us for an extended period of time. The blockchain concept can be utilized to conduct real-time analysis on how much our power grid system is carrying at a particular time. The results of such an evaluation can help determine which existing lines face substantial overloads.

The blockchain concept is ideal as it can take into consideration many other factors such as the population density, geographic location, and the general profile of an area in coming up with proposals on what to do to resolve and protect the grid from catastrophic failures. For instance, real-time data can be collected from the ground and transmitted to servers from where the data is analyzed on potential areas that require an upgrade. It can also come up with solutions such as the need to construct microgrids that can help serve a community better.

The blockchain concept is such an ideal solution in our time. The recently propagated concept of developing electric vehicles which need charging in designated charging stations is fully supported by the idea of integrating technology and microgrids within our power grid system. A blockchain-integrated power grid can, for instance, remotely alert electric vehicle drivers on the next charging stations from where they can power up their vehicles.

Also, the technology makes it possible for electrical engineers and maintenance officers in the national power grid system to monitor the performance of the entire system remotely. Potential failures identified such as voltage spikes that often cause fires can then be identified and warnings sent to nearby fire stations from where precautionary measures can be taken. Through the blockchain data processing concept, the system can also be tuned to propose particular areas which are highly vulnerable to voltage spikes, thereby helping come up with proposals on how microgrids such as green power sources like wind and solar power can be integrated into the system for better performance.
