Summary: As the U.S. aims to reduce carbon emissions and achieve energy independence, solar power emerges as a key technology. However, the transition faces high costs and economic challenges, with solar electricity generation currently more expensive than traditional methods. This article delves into the financial and technological hurdles of solar power, exploring the need for innovation and efficient market strategies to make solar energy economically viable.
The push towards renewable energy, particularly solar power, is gaining momentum in the United States as part of a broader strategy to curb carbon dioxide emissions and reduce reliance on foreign oil imports. Despite the environmental benefits, the economic viability of solar power remains a significant challenge. The cost of electricity generated from solar power is considerably higher than that from conventional sources. For instance, current production costs for solar electricity can be as high as $0.50 per kWh, compared to the average U.S. retail price of about $0.095 per kWh Energy Information Administration.
Solar power technology can be broadly categorized into two main types: photovoltaic (PV) systems that convert sunlight directly into electricity, and thermal systems that convert sunlight to heat, which then generates electricity. Each method has its own set of challenges and costs associated with it.

Thermal Systems:
IBM has recently proposed a hybrid approach that concentrates sunlight onto smaller, more efficient panels, potentially reducing material costs but requiring sophisticated cooling systems to manage heat IBM Research.
The transition to solar power involves substantial upfront investments and, currently, higher electricity costs for consumers. This financial burden often falls on unsuspecting consumers through hidden charges or increased tariffs. Effective regulation and transparent policies are essential to ensure that consumers are not unfairly penalized during this transition phase.
The solar power sector is experiencing a boom, with numerous new installations being announced. However, these developments come with high financial stakes. The cost of installing solar capacity ranges from $3,000 to $7,500 per kW, translating to a production cost of $0.30 to $0.60 per kWh. This is significantly higher than other electricity generation technologies.
To foster a more competitive solar market, government incentives and regulatory frameworks play a crucial role. By providing income guarantees and subsidies, the government can help shorten the cost reduction phase for solar technologies, making them more competitive with traditional energy sources. However, this approach must be balanced to ensure that it does not lead to market distortions or excessive financial burdens on consumers.
Despite the current economic challenges, the future of solar power looks promising due to ongoing technological advancements and increasing societal demand for sustainable energy solutions. Innovations in energy storage and more efficient solar cells could dramatically reduce costs and improve the reliability of solar power.
As solar and other intermittent renewable energy sources grow, developing efficient energy storage solutions becomes critical. These technologies are essential to manage the variability of solar power and ensure a stable energy supply. Advances in battery technology and other forms of energy storage are key areas for investment and innovation.
While solar power presents an environmentally friendly alternative to fossil fuels, its economic viability is still a work in progress. By addressing technological challenges, improving regulatory frameworks, and fostering market competition, solar power can become a cornerstone of a sustainable energy future. The journey towards affordable solar energy requires a collaborative effort among governments, businesses, and consumers to harness the full potential of this abundant natural resource.
The Electric Car Crapshoot
Electric cars are promoted as saviors of the energy crisis. Unfortunately, they are expensive, will not reduce foreign oil imports, and will contribute to continuing, global overheating. The US needs a new, science based energy policy. Taxpayers must demand development of thermally more efficient combustion engines. Production of renewable, affordable, and storable liquid fuels must be pursued by an independent government agency.
Obama's Energy Policy and the Challenges of Energy Science
In the wake of the 2008 financial crisis, President-elect Barack Obama pledged to revitalize America's energy policy, emphasizing the need for a sustainable and scientifically sound approach. As he assembled his team, the urgency to address both economic and environmental challenges was clear. This article explores the intricacies of Obama's energy strategy, the scientific debates surrounding it, and the broader implications for future policy-making.
Saving Jobs by Saving General Motors
General Motors is facing bankruptcy and liquidation. Only a drastic, deeply cutting reorganization can save the company from certain death. Investors, board, management, and union are responsible for past decay and must be removed. Board and management must resign. Investors must sell their stock. Union members should receive a negotiated buyout. A new, reenergized, unshackled, and internationally competitive company must reemerge.
