Key Takeaways
- Energy is the capacity to do work, measured in joules or kilowatt-hours, and powers everything from your phone to your car.
- Fossil fuels (coal, oil, natural gas) still dominate global energy production, accounting for roughly 75% of the total in 2025.
- Renewable energy sources like solar and wind are rapidly growing, with solar power expected to generate 30% of Georgia’s electricity by 2030.
- Understanding energy policy, such as net metering for solar panels, can help you make informed decisions and potentially save money.
What Exactly is Energy?
At its most basic, energy is the ability to do work. Think of it as the force that makes things happen. It comes in many forms, including:
- Kinetic energy: The energy of motion (like a speeding car).
- Potential energy: Stored energy (like water held behind a dam).
- Thermal energy: Heat energy (like the warmth from a fire).
- Chemical energy: Energy stored in the bonds of atoms and molecules (like the gasoline in your car).
- Electrical energy: The flow of electric charge (like the electricity powering your lights).
We measure energy in different units depending on the context. Joules (J) are the standard unit in physics, but kilowatt-hours (kWh) are more commonly used for measuring electricity consumption. One kWh is the amount of energy used by a 1,000-watt appliance running for one hour. Your monthly electricity bill reflects your kWh usage.
The Energy Landscape in 2026
The global energy mix is a complex tapestry woven from various sources. Fossil fuels – coal, oil, and natural gas – have historically been the dominant players. According to the International Energy Agency (IEA) [link to iea.org], fossil fuels still accounted for a significant portion of global energy consumption in 2025, roughly 75%. However, this is slowly changing. If you are interested in the future economic trends, you should keep reading.
Renewable energy sources are gaining ground. Solar, wind, hydro, and geothermal power are becoming increasingly competitive, driven by technological advancements and falling costs. The growth is particularly noticeable in solar power, which has seen exponential growth in recent years.
Here in Georgia, we’re seeing a similar trend. Georgia Power [link to georgiapower.com] is investing heavily in solar energy, and many homeowners are installing rooftop solar panels. The goal is to have solar energy generate 30% of the state’s electricity by 2030.
Fossil Fuels: The Old Guard
Despite the rise of renewables, fossil fuels remain a significant part of our energy supply. Each has its own advantages and disadvantages:
- Coal: Abundant and relatively inexpensive, but also the most polluting fossil fuel. Burning coal releases significant amounts of carbon dioxide and other harmful pollutants.
- Oil: A versatile fuel used for transportation, heating, and electricity generation. However, oil is a finite resource, and its extraction and transportation can have environmental consequences.
- Natural Gas: Cleaner-burning than coal and oil, natural gas is often used for electricity generation and heating. It’s also a key component in the production of many chemicals and plastics.
There’s a lot of debate about the future of fossil fuels. Some argue that they are essential for meeting our energy needs, while others advocate for a rapid transition to renewables. One thing is clear: the use of fossil fuels needs to become more sustainable if we want to mitigate climate change. Carbon capture and storage technologies are one potential solution, but they are still under development.
Renewable Energy: The Rising Star
Renewable energy sources offer a cleaner, more sustainable alternative to fossil fuels. Here are some of the most common types:
- Solar Power: Harnessing the sun’s energy through photovoltaic (PV) cells. Solar panels convert sunlight directly into electricity.
- Wind Power: Using wind turbines to convert wind energy into electricity. Wind farms are becoming increasingly common in many parts of the world.
- Hydropower: Generating electricity from the flow of water. Dams are the most common form of hydropower, but there are also run-of-river hydro projects that have less environmental impact.
- Geothermal Energy: Tapping into the Earth’s internal heat to generate electricity or heat buildings. Geothermal energy is a reliable and sustainable source of power.
- Biomass Energy: Burning organic matter, such as wood or crops, to generate electricity or heat. Biomass energy can be carbon neutral if the biomass is sustainably sourced.
The cost of renewable energy has plummeted in recent years, making it increasingly competitive with fossil fuels. Solar and wind are now often the cheapest sources of new electricity generation. This is driving a rapid expansion of renewable energy capacity around the world. Understanding trade agreements is also important in this space.
One challenge with renewable energy is its intermittency. Solar and wind power are dependent on the weather, which can fluctuate. This means that we need to develop energy storage solutions, such as batteries, to ensure a reliable supply of electricity. Battery technology has improved tremendously in the past decade.
I had a client last year who lived off exit 7 on I-75. They installed a Tesla Powerwall [link to tesla.com] with their solar panels. The system allows them to store excess solar energy during the day and use it at night or during power outages. They are saving about $200 per month on their electricity bill and are also reducing their carbon footprint.
Understanding Energy Policy
Energy policy plays a crucial role in shaping the energy landscape. Governments can incentivize the development of renewable energy through tax credits, subsidies, and regulations. They can also disincentivize the use of fossil fuels through carbon taxes or emission standards. This can be especially important for manufacturing’s risky business.
Here are some key energy policy concepts:
- Net Metering: Allows homeowners with solar panels to sell excess electricity back to the grid. This can help offset the cost of installing solar panels and encourage the adoption of renewable energy.
- Renewable Portfolio Standards (RPS): Require utilities to generate a certain percentage of their electricity from renewable sources. Georgia does not have a mandatory RPS, though Georgia Power is working toward renewable goals.
- Carbon Tax: A tax on the carbon content of fossil fuels. This is designed to make fossil fuels more expensive and encourage the adoption of cleaner energy sources.
- Cap-and-Trade: A system that sets a limit on the total amount of greenhouse gas emissions and allows companies to trade emission allowances.
We ran into this exact issue at my previous firm. A developer wanted to build a large solar farm near the intersection of Northside Drive and I-285. However, they were facing opposition from some local residents who were concerned about the visual impact of the project. We worked with the developer to address these concerns and ultimately secured the necessary permits. It took nearly 18 months and cost roughly $75,000 in legal and consulting fees.
