This makes it ideal for urban dwellers with minimal outdoor space or those looking to maximise productivity in smaller gardens.

Resource conservation – Garage gardening promotes resource conservation by minimising water use, reducing reliance on synthetic pesticides and fertilisers, and optimising energy efficiency through sustainable practices. By adopting eco-friendly gardening techniques, enthusiasts can minimise their carbon footprint while reaping the rewards of a bountiful harvest.

Environmental Impact of Traditional Energy Sources

Conventional energy sources such as fossil fuels (coal, natural gas and oil), nuclear power and non-renewable grid electricity are commonly used to power indoor horticulture facilities. While these sources provide the energy needed to support indoor growing, they also have significant environmental impacts.

Greenhouse gas emissions – The combustion of fossil fuels releases greenhouse gases such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) into the atmosphere. These gases trap heat and contribute to global warming and climate change, leading to adverse environmental impacts such as rising temperatures, changes in rainfall patterns and sea level rise.

Air pollution – Burning fossil fuels for energy releases pollutants such as sulphur dioxide (SO2), nitrogen oxides (NOx) and particulate matter into the air. These pollutants can adversely affect air quality, human health and ecosystems, leading to respiratory diseases, smog formation, acid rain and damage to vegetation.

Resource depletion – The extraction and processing of fossil fuels for energy can have significant environmental impacts, including habitat destruction, water and soil pollution. In addition, fossil fuel reserves are finite and non-renewable, meaning that continued reliance on these sources depletes natural resources and exacerbates environmental degradation.

Water use – Conventional energy production methods, such as coal-fired power plants and nuclear reactors, require large amounts of water for cooling. This can lead to water scarcity, habitat disturbance and adverse impacts on aquatic ecosystems, particularly in regions with limited freshwater resources or fragile ecosystems.

Waste generation – The extraction and combustion of fossil fuels generates various forms of waste, including ash, sludge and radioactive by-products. Improper disposal of these wastes can contaminate soil, water and air, posing risks to human health and the environment. In addition, the long-term storage and management of radioactive waste from nuclear power plants pose significant challenges and environmental risks.

Land use and habitat loss – The extraction, transport and processing of fossil fuels often requires extensive land use and infrastructure development, leading to habitat loss, deforestation and fragmentation of natural landscapes. This can have negative impacts on biodiversity, ecosystem services and the resilience of natural ecosystems to climate change.

Non-renewable energy sources such as fossil fuels (coal, oil and natural gas) have a significant impact on the environment, contributing to both carbon emissions and resource depletion.

Carbon Footprint

Greenhouse gas emissions – Burning fossil fuels releases carbon dioxide (CO2) and other greenhouse gases into the atmosphere. These gases trap heat, leading to global warming and climate change.
Major contributor to climate change – Fossil fuels are the world’s largest source of man-made greenhouse gas emissions. They account for about 75% of total greenhouse gas emissions, primarily from energy-related activities such as electricity generation, transportation and industrial processes.
Long-term impacts – The build-up of CO2 and other greenhouse gases in the atmosphere leads to long-term environmental changes, including rising temperatures, changes in precipitation patterns, melting ice caps and rising sea levels. These changes have far-reaching effects on ecosystems, weather patterns, agriculture and human societies.

Resource Depletion

Finite reserves – Fossil fuels are non-renewable resources, which means they are finite and will eventually run out. As global demand for energy continues to rise, the extraction and consumption of fossil fuels is depleting finite reserves, leading to concerns about future energy security and availability.
Environmental degradation – The extraction, processing and transportation of fossil fuels can have significant environmental impacts, including habitat destruction, water and soil pollution, and disruption of ecosystems. For example, mountaintop removal coal mining and oil spills from offshore drilling can have devastating impacts on local ecosystems and wildlife.
Conflict and instability – Competition for access to fossil fuel reserves can lead to geopolitical tensions, conflict and instability in regions rich in these resources. In addition, reliance on fossil fuel imports can make countries vulnerable to supply disruptions and price volatility in the global energy market.

– Solar panels, also known as photovoltaic (PV) modules, consist of individual solar cells made from semiconductor materials such as silicon.
– These solar cells absorb sunlight and convert it into direct current (DC) electricity through the photovoltaic effect.

Mounting systems
– Solar panels are typically mounted on a stable support structure, such as the roof of a garage or a ground-mounted frame adjacent to the building.
– Rooftop mounting systems may include special racks or frames attached to the roof structure, allowing for optimal orientation and tilt angle to maximise exposure to sunlight.
– Ground-mounted systems offer flexibility in installation and positioning, allowing adjustments to accommodate shading, terrain and aesthetic preferences.

Inverter and electrical components
– The direct current (DC) electricity generated by the solar panels is fed into an inverter, which converts it into alternating current (AC) electricity suitable for household appliances and electrical systems.
– Electrical wiring and components, including circuit breakers, disconnects and meters, are installed to connect the solar panels to the building’s electrical system.

Net metering and grid connection
– With grid-connected solar PV systems, excess electricity generated by the solar panels can be fed back into the electrical grid through a bi-directional meter.
– This allows homeowners to receive credit for the excess electricity exported to the grid, effectively offsetting their electricity consumption when there is insufficient sunlight, such as at night or on cloudy days.

Monitoring and maintenance
– Solar PV systems may include monitoring equipment to track electricity production, system performance and energy savings over time.
– Routine maintenance, such as cleaning solar panels to remove dirt and debris, inspecting electrical connections, and ensuring proper ventilation around the panels, is essential to maximise system efficiency and longevity.
