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.

The Impact of the Oil & Natural Gas Industry on the Economy

Oil and natural gas are two of the most commonly used raw materials available. When it comes to numbers and dollar values, the industry is considered to be one of the largest sectors of the economy worldwide. Every day billions of dollars are generated through the oil and gas business, and petroleum-based products are in high demand.  

Supports Employment 

The oil and natural gas industry is a great supporter of employment opportunities. Job growth and availability is a key component of success within the economy, and as the industry continues to thrive, it opens up various employment opportunities. Consider the operation of the oil and gas industry overall; the process of producing involves many different moving parts. For example, labor-intensive jobs alone, like drilling crews, mechanics, and operators are all essential in the process. In general, the oil and gas industry is responsible for supporting roughly 10 million jobs.

Production Costs 

Production and manufacturing costs are heavily influenced by the price of oil and natural gas. An increase or decrease in pricing can significantly impact the domestic economy. Low oil prices generally mean lower costs for transportation. Additionally, lower oil prices can lead to a significant decrease in manufacturing costs as well. An increase in price tends to add to the cost of conducting regular business. “Conversely, high oil prices add to the costs of doing business. Whether it is higher cab fares, more expensive airline tickets, the cost of apples shipped from California, or new furniture shipped from China, high oil prices can result in higher prices for seemingly unrelated products and services.”

How Can Solar Energy Benefit the Environment?

Environmental concern is increasing rapidly, and people are trying to do what they can to be more environmentally conscious. Renewable energies have become a significant focus for many homeowners, business owners, and large corporations across the United States. Solar energy, for example, is being widely used by big businesses and regular homeowners to preserve energy and become more environmentally friendly. Here are a few ways solar energy can benefit the environment:

Can Improve Health 

The use of solar energy can drastically decrease the potential for air pollution. Air pollutants are often responsible for many respiratory illnesses and cardiovascular problems. The widespread use of solar energy would significantly reduce the emittance of nitrous oxide and sulfur dioxide, both of which can cause serious health problems. Overall, solar panels can be used as a source of energy that won’t contribute to air pollution. 

Reduce Greenhouse Gasses

Greenhouse gasses are produced when fossil fuels burn; they are one of the main contributors to an increase in global temperatures and climate change. Your carbon footprint and greenhouse gas emissions are significantly reduced by the use of solar energy and other renewable forms. According to Vivint Solar, “As the carbon count continues to increase, so will our retention of heat from the sun. These changing air conditions will continue to affect different climates, causing some to warm, others to cool, and causing weather patterns everywhere to become more sudden and volatile.”

Is Wave Power the New Solar?

Is Wave Power the New Solar_ _ Blake Zimmerman Houston

Out With the Old, In With the New?

Solar energy is a great way to generate usable energy from a source that is readily available to most places. Though solar energy is great it is not always the best option for certain places. Therefore, many other forms of renewable energy are being researched. One of the most profound sources of energy currently is wave energy.

Wave Energy

Waves are created by a variety of environmental forces. The most common force that people know is the force of wind, which creates waves as it hits the surface of the water. Gravitational pull, the force generated by the interactions between the sun, earth, and moon, is also responsible for the creation of waves. These waves, though created by energy that moves through water, also generate energy.


Wave energy can be captured by a system that utilizes attenuators, a device that works opposite to the way that an amplifier works. The wave energy is captured by attenuators that sit perpendicular to the direction of the moving waves. As the waves continue to move along the body of the attenuator, the attenuator continues to move as well. The movement of the attenuator transfers to a hydraulic pump which then converts the wave energy into usable energy.


Absorber systems utilize buoys to capture wave energy from the surface of the water. The energy is transferred through a series of cables and underwater devices to an undersea substation. A linear or rotary generator is then used to convert the energy into a usable form of electric energy.

Water Columns

Oscillation water columns (OWC) use a combination of water, air, and gravity to create pressure within the column system. Air is transferred as the system is continually pressurized and depressurized. The transferred air is then pulled into an air turbine which subsequently converts the energy into usable energy.


There are two types of devices that can be used to convert wave energy: overtopping devices and inverted-pendulum devices. Overtopping devices utilize turbine systems to drain water and convert the mechanical energy into electrical energy. Inverted-pendulum devices, as suggested by their name, use an upside-down pendulum device to sway with waves. A series of hydraulic pumps and electric generators then convert the energy transferred by the inverted-pendulum device.
