Energy Resources & Consumption
How could a local government best support community-level transitions toward greater use of solar energy?
Decreasing property taxes across the board irrespective of renewable energy installations.
Banning rooftop gardens that may potentially shade neighboring photovoltaic arrays.
Implementing zoning regulations that require or favor installation of photovoltaic systems on new constructions.
Imposing additional sales taxes on all electricity sales regardless of source generation method.
What type of international agreement would foster widespread adoption of high-capacity solar farms in developing countries?
Mandatory export quotas for rare earth minerals crucial for PV manufacturing
Subsidies exclusively for domestic solid waste management facilities
Bilateral trade agreements focused only on oil and gas exploration activities
Developing an international carbon credit trading scheme that rewards investments in renewables
What is a drawback of solar energy when it comes to electricity storage?
The need for a storage system for electricity fluctuates
There is no need for a storage system for electricity
There is a need for a storage system for electricity
There is a limited need for a storage system for electricity
Considering thermodynamics, why might concentrating solar power (CSP) systems have a larger ecological footprint than photovoltaic (PV) systems?
PV systems convert more sunlight into thermal energy leading to higher heat waste around them.
CSP systems inherently produce more COâ‚‚ per kilowatt-hour due to lower conversion efficiencies from sunlight to electricity.
PV systems typically need batteries that have high embodied energy costs contributing significantly to their footprint.
CSP systems often require water cooling, which can strain local water resources in arid regions where they're commonly located.
How does the location of a building affect the efficiency of passive solar heating design?
Distance from urban areas to minimize light pollution.
Direction to face sunlight for maximum exposure.
Elevation above sea level for reduced resistance.
Proximity to natural bodies of water for enhanced cooling effects.
What environmental impact might be a concern for large-scale deployment of solar farms?
Habitat disruption and land use changes.
Significant water pollution from panel manufacturing.
High carbon dioxide emissions during operation.
Excessive noise pollution during peak sunlight hours.
How is solar energy harnessed?
Through the use of wind turbines
Through the use of nuclear reactors
Through the use of solar panels made up of photovoltaic cells
Through the use of hydroelectric dams

How does the incorporation of thermal storage systems in concentrated solar power (CSP) plants affect their energy output?
It increases maintenance costs without changing energy output levels significantly.
It increases reliability by allowing energy production when sunlight is not available.
It reduces output by taking up space that could be used for more mirrors or lenses.
It decreases overall efficiency due to heat loss over time.
What is a potential negative effect on biodiversity that could result from the installation of large-scale solar panel arrays in desert environments?
Displacement or fragmentation of sensitive desert species' habitats could occur.
Acidic soil conditions develop due to chemical leaching from solar panels, threatening plant diversity.
Increased shade from panels leads to an overgrowth of vegetation unsuitable for desert species.
Desert areas experience lower temperatures due to reflective surfaces, altering animal migration patterns dramatically.
Which factor would most significantly increase the energy return on investment (EROI) for a new solar farm project?
Optimization of panel angle to maximize sun exposure year-round.
Use of cheaper, less efficient photovoltaic materials to reduce costs.
Installation of panels in areas with high average cloud cover.
Frequent replacement of panels with the latest technology.
