The purpose of a renewable energy project is to generate power without using finite resources (such as coal) for fuel; thereby minimising the power sector’s overall emission levels and reliance on high impact activities (such as mining).
The challenge with renewable energy is to manage intermittency and to be sure that the renewable projects that we pursue don’t also generate an unacceptable level of negative consequences (such as excessive land clearing).
Renewable technologies include hydro-electric, solar, wind, biomass, geothermal and ocean power.
Renewables engineers like those at 786 Fuel play a crucial role in advancing the use of sustainable energy technology and contributing to the global transition towards a cleaner and more sustainable energy future.
They design, develop, and implement systems and technologies that harness renewable sources of energy, such as solar, wind, hydroelectric, geothermal, and biomass energy.
The goal of renewables work is to create sustainable and environmentally-friendly solutions for meeting the world’s energy needs.

Here are some key renewable energy technologies.
Solar power systems covert solar radiation into electricity.
Solar PV (Photo Voltaic) systems utilise semi-conductors (solar cells). When a photon of light hits a solar cell, electrons jump over a PN junction (in the semi-conductor) and create a voltage differential over that junction.
Solar thermal systems utilise the heat from direct solar radiation (concentrated with mirrors) to generate steam to drive a turbine.
Wind turbines capture the kinetic energy of wind and convert it into electricity. As the wind blows, it spins the turbine blades, which turn a generator and produce electricity. Wind farms consist of multiple turbines that are connected to an electrical grid.
Hydro-electric power systems utilise the gravitational potential energy of water held at an elevation.
The water might be held in an reservoir on a plateau, flow through penstocks to a set of turbines (generating power) and then be released into a river in a valley.
Hydro-electric schemes require high rainfall or snow melt to generate primary energy.
Hydro-electric schemes can also be used for energy storage (pumped hydro energy storage or PHES). In this arrangement, surplus power is used to pump water to the upper reservoir where it is stored until periods of peak demand, when it is released to generate power.
A PHES scheme is not in itself a renewable source, it does however facilitate renewables by being able to store surplus energy for use when the renewable source is not available.
Biomass energy utilises organic matter such as wood, agricultural waste, and dedicated energy crops to produce heat, electricity, or biofuels. Biomass can be burned directly, converted into biogas through anaerobic digestion, or transformed into liquid biofuels through processes like fermentation or pyrolysis.
Geothermal energy utilises heat from within the Earth to generate electricity or provide heating and cooling. Geothermal power plants tap into hot water or steam reservoirs underground and convert the geothermal energy into electricity through steam turbines.
Geothermal systems are more economical in areas with high volcanic activity such as New Zealand, the Philippines and Iceland.
Ocean energy technologies capture energy from ocean waves and tidal currents or temperature differences.
Wave energy converters extract energy from the motion of ocean waves.
Tidal turbines harness the kinetic energy of tidal currents.
We design and analyse renewable energy systems, considering factors such as site location, available resources (sunlight, wind, water, etc.), energy demand, and environmental considerations. We use computer simulations and modelling tools to optimise system performance.
We do this with a view on whole of life project value in order to maximise investor returns.

Renewable energy markets refer to the economic systems and mechanisms that facilitate the production, distribution, and consumption of renewable energy. These markets have evolved and expanded as renewable energy technologies have become more efficient, cost-effective, and widespread.
Here are some key aspects of renewable energy markets.
The growth of renewable energy markets is driven by factors such as declining costs of renewable technologies, increasing environmental awareness, policy support, and the recognition of the economic and social benefits of renewable energy.
The renewable energy market requires large energy consumers and energy retailers to surrender renewable energy certificates.
Renewable energy markets involve the generation and production of electricity or other forms of energy from renewable sources. This includes the operation of renewable energy power plants such as solar farms, wind farms, hydroelectric facilities, biomass plants, and geothermal plants.
Renewable energy is increasingly integrated into existing energy markets, such as wholesale electricity markets, where renewable energy generators compete with traditional fossil fuel generators to sell their electricity. Market mechanisms, such as auctions and power exchanges, facilitate the trading and price discovery of renewable energy.
The growth of renewable energy markets is closely tied to advancements in energy storage technologies. Energy storage systems, such as batteries, allow for better management of intermittent renewable energy sources, enabling the storage and utilization of excess energy during periods of low demand or high renewable generation.
RECs, also known as green certificates or tradable renewable certificates, are tradable instruments that represent the environmental attributes associated with renewable energy generation. They allow consumers to support renewable energy by purchasing and retiring RECs, which help finance renewable energy projects.
Governments often provide incentives to promote renewable energy generation. Feed-in tariffs (FITs) guarantee a fixed payment rate for renewable energy producers, while power purchase agreements (PPAs) establish long-term contracts between renewable energy generators and consumers.
Many countries and regions have established renewable portfolio standards or targets that mandate a certain percentage of electricity generation to come from renewable sources. These policies provide regulatory frameworks and market incentives to encourage renewable energy development.
Renewable energy markets involve international trade and investments, with countries importing and exporting renewable energy technologies, equipment, and expertise. Global cooperation and collaborations are crucial for sharing best practices, financing renewable energy projects, and accelerating the adoption of renewable energy worldwide.
Renewable energy markets also support distributed generation, where energy is produced at or near the point of consumption. This includes rooftop solar installations, small wind turbines, and community-based renewable energy projects. Microgrids, which are localized energy systems that can operate independently or in conjunction with the main grid, often incorporate renewable energy sources.
