Chapter 1: Introduction to Climate Solutions

We possess nearly all the necessary solutions to combat climate issues; the challenge lies in their execution.

This paragraph will result in an indented block of text, typically used for quoting other text.

Electrifying Everything

Transition all energy services to utilize electricity instead of fossil fuels across transportation, industry, and agriculture. This means phasing out gas appliances, converting all ground transport to electric, and ensuring that shorter-haul aviation and maritime transport operate on batteries. Biofuels should be reserved for longer-haul aviation and shipping that cannot be electrified. All heating needs—residential, commercial, and industrial—should also be met with electricity.

The global energy system wastes over two-thirds of primary energy, primarily as waste heat from inefficient fossil fuel combustion processes. We only need to replace about one-third of the primary energy we currently consume to sustain our lifestyle and economy.

Expanding Renewable Energy Generation

Every other form of energy generation, excluding nuclear, has been overbuilt; we should apply the same principle to wind and solar. These sources are cost-effective, making expansion financially viable. Additionally, we should invest in more hydroelectric power, geothermal energy, and some biomass.

Building Comprehensive Electrical Grids

Enhancing current electrical grids and developing continent-wide electrical markets is essential. High-voltage direct current (HVDC) technology is crucial for efficient long-distance power transmission. We should upgrade alternating current (AC) systems to HVDC, bury HVDC lines along existing rights-of-way, and connect continents through this technology.

Enhancing Electricity Storage Solutions

While concerns about electricity storage are often exaggerated due to the abundance of renewables and expansive grids, some storage remains necessary. Implementing closed-loop, off-river pumped hydro storage is efficient and offers significant potential. Existing hydroelectric dams can also be adapted for passive, on-demand storage. Fast-response grid storage can utilize lithium-ion and similar battery technologies, while redox flow batteries can bridge the gap between cell-based and pumped hydro storage.

Reforesting the Planet

Human activity has led to the loss of around 50% of the six trillion trees that once flourished on Earth. Planting a trillion new trees can significantly help combat climate change, as each tree absorbs approximately one ton of CO2 from the atmosphere over 40 years.

Transforming Agricultural Practices

Adopting low-tillage farming techniques can enhance CO2 retention in the soil, with a portion potentially becoming permanently sequestered. Universal precision agriculture and advancements in agrigenetics can reduce reliance on CO2-elevating nitrogen fertilizers, while subsistence farming should be phased out.

Revolutionizing Concrete, Steel, and Industrial Processes

Cement production is responsible for about 8% of global CO2 emissions, primarily due to energy consumption and the release of CO2 when limestone is converted into quicklime. Transitioning to electric heat for cement production or utilizing biomethane from landfills is crucial. Capturing CO2 emissions from limestone kilns presents one of the few viable carbon capture opportunities.

Steel production can be improved by recycling fossil fuel infrastructure, such as scrapping cars and pipelines, to create new steel using electric minimills. Green hydrogen can play a role in the limited new steel production needed.

Pricing Carbon Effectively

Encouraging a shift away from high CO2 emissions requires making it financially burdensome to emit carbon. Implementing aggressive carbon pricing is an effective strategy.

Phasing Out Coal and Gas Power

The phase-out of coal is already underway, yet it remains the largest single source of CO2 emissions. Regulations should further eliminate coal plants. For natural gas, we must minimize upstream methane leaks, limit the construction of gas plants, and shift towards biologically sourced methane.

Ending Fossil Fuel Subsidies

We must cease financing and subsidizing fossil fuel exploration, extraction, and usage. The U.S. alone allocates tens of billions annually for fossil fuel subsidies with little action taken since 2009 to eliminate them. Progress on commitments made by the G7 and G20 to eradicate subsidies has been slow. Instead, we should redirect funds toward addressing the industry's environmental impact.

Eliminating High-Global Warming Potential Refrigerants

Switching refrigerants such as R410a to propane and CO2 is essential. The Kigali Amendment to the Montreal Protocol targets harmful HFCs, which can have a global warming potential 2,000 to 4,000 times greater than CO2. Project Drawdown identifies this as the top solution in terms of cost-benefit analysis.

Ignoring Distracting Solutions

Nuclear energy is slow to develop and costly. Even China has seen stagnation in nuclear deployment since 2018, while renewables have grown exponentially. While we should appreciate every new nuclear reactor for its low-carbon output, our focus should remain on renewable energy sources.

Mechanical carbon capture and sequestration (CCS) often proves ineffective, merely relocating CO2 without addressing emissions meaningfully. We should discontinue viewing it as a scalable solution.

Hydrogen presents more challenges than solutions, acting primarily as an inefficient energy store that serves the fossil fuel sector. The annual usage of black hydrogen leads to significant CO2 emissions, primarily in oil refineries.

Air-to-fuel technologies, such as direct air capture paired with hydrogen electrolysis, are also misguided, being more costly and emitting more CO2 than electrification.

Understanding Motivations Behind Climate Strategies

This analysis is based on empirical evidence and is not rocket science. When recommendations diverge from these effective solutions, it's essential to scrutinize the motivations of the involved parties, particularly regarding potential financial losses or gains.

We already have the solutions at our disposal. What we lack is the collective will to implement them, which is often undermined by the fossil fuel industry that resists this necessary transition.
