You're looking to manage your energy more efficiently. Which renewable energy systems should you consider?

RE sources such as solar PV system to generate electricity don't make the plant more energy efficient but only getting greener energy supply with reduced GHG emission. Energy efficiency can only be achieved from more energy efficient operations, higher efficiency energy using systems and equipment and systematically implemented energy management program with clear objectives and targets.

The sun is an abundant and virtually inexhaustible source of energy. It radiates an enormous amount of energy every day, providing an almost limitless supply for harnessing through solar technologies.The use of solar power significantly reduces carbon footprints. Solar panels generate electricity without emitting carbon dioxide or other harmful pollutants, making them a crucial element in efforts to mitigate climate change and achieve sustainability goals. Once installed, solar power systems generally have low operating and maintenance costs. Unlike other power source, solar panels require minimal maintenance, mainly cleaning to ensure optimal performance.

Actualmente, la energía solar fotovoltaica, es la Energía Renovable más conveniente desde varios puntos de vista. El costo de los paneles FV viene en descenso, al mismo tiempo que su eficiencia de generación va incrementándose. A su vez, la FV tiene grandes ventajas, por su simplificidad y menor costo de mantenimiento en su Ciclo de Vida.

The title for this article should rather be: "You're looking to decarbonize your energy portfolio or footprint. Which renewable energy systems should you consider?" In this case, the list of RETs will remain as it is. Alternatively, the title could be: "You're looking to manage your energy more efficiently. Which energy conservation measures should you consider?" In this case, the list would include both active and passive measures but the list could be very long unless it is narrowed down to those that usually have the most significant impact on energy consumption.

I've been in the solar industry since 2009, it started as an expensive source of energy with an LCOE (levelized cost of energy) much higher than coal or gas, therefore initially it has been subsidized (I remember a panel had a price of 3 USD/Wp back in 2009, nowadays price is lower than 0.15 USD/Wp, incredible!). Then thanks to global increase of installation and especially due to increase in capacity in Asia it has gone through an heavy rump up and it is now the cheapest source of energy surpassing by far the conventional (and dirty) sources. What's happening is a real revolution in which consumers become prosumers (they can produce and consume their energy) and can benefit from a much lower cost, contributing to lowering CO2 emissions.

Advances in technology and increased efficiency have led to a significant reduction in the cost of harnessing wind power, making it increasingly competitive with conventional energy sources. Wind power projects can be easily scaled up or down, making them adaptable to various energy demands and geographical locations.

As aplica??es de energia eólica s?o, de maneira geral, mais restritas a aplica??es de grande porte, como usinas. As aplica??es de pequeno porte, especialmente em áreas urbanas, n?o tem se demonstrado viável quando comparado com outras alternativas, como a fotovoltaica, por uma série de quest?es, dentre elas: - Perfil de vento, que é afetado pela arquitetura urbana, tornando-o mais turbulento e com menor velocidade - Ocupa??o de área útil - Necessidade de infraestrutura maior - Ruído e vibra??o - Maior custo de manuten??o - Menor vida útil

Wind power requires proper location and space as well as higher investment costs where the energy output potential needs to be analysed to yield good ROI.

Comparatively less consistency in power generation.. Require more space at an identified location.depending on wind velocity which is varying through out the day

La energía eólica tiene mayor número de horas de operación y producción (especialmente interesante su combinación con la producción solar) y puede instalarse en zonas marítimas (off-shore wind) permitiendo una mayor eficiencia respecto a la producción on-shore. Sin embargo, presenta desventajas a considerar: - O&M elevado - CAPEX mucho mayor que para instalaciones FV (aún más en off-shore wind) - Mayor probabilidad de averías al constar de muchos elementos móviles y vibraciones - Mercado de proveedores y disponibilidad más reducido

Hydro power is one of the oldest ways to get power.it requires very high capex & infrastructure. Some of the issues like land acquisition, relocation of people are associated with hydro projects

La energía hidroeléctrica es una de las energías renovables que requiere de una mayor infraestructura civil debido a esto se debe tener muy en cuenta la situación geográfica en la cual se planea implantar la hidroeléctrica ya que debe cumplir con algunos requisitos base como tiempo de retorno de crecidas , garantizar que el caudal será suficiente para el funcionamiento de la hidroelectrica incluso en tiempo de sequía entre otras cosas siendo así esta energía renovable muy beneficiosa si se implanta en un lugar correcto.

I would prefer hydro as I am hydril professional in energy management ambit as I think no intermittent issue plus a lot of stuff integrated, no bad effects on environment no hazards.If geographical hindrance is removed the hydro is the best option.

Hydro electric power could be the least expensive way to generate power after the initial costs. Obviously, it is not available everywhere like solar power and has to be centralized around damns and natural bodies of water. It could be used though in many places where it is possible to build a high reservoir which is used as potential energy storage for water pumped by solar or wind energy. The reservoir will act as the battery pack.

Installing renewable energy systems is a terrific method to lower greenhouse gas emissions, save energy costs, and improve energy efficiency. Considering the previously listed aspects, you may choose the best renewable energy system. Hydropower is a renewable energy source that produces electricity using water. It can be separated into two categories: run-of-the-river systems or micro-hydro generators are used in small-scale hydropower. In contrast, dams and reservoirs are used in large-scale hydropower. Hydroelectric power facilities are constructed on top of rivers and reservoirs. Utilized for generations, hydroelectric power is a clean, renewable energy source.

Biomass Power is a mode of Power Generation utilizing waste materials like Agriculture Waste, Animal Waste, Wood, Municipal Waste etc. Though burning of biomass/waste is a chief source of power generation, but other processes like Gasification are also catching up gradually. Meeting stringent norms of Pollution Control and getting appropriate Tariff are some of the challenges to be overcome.

This is the most economical way to generate power precisely for domestic usage. It has some hidden benefits like proper disposal of waste, less technical know how to set up etc.

When managing energy efficiently, biomass power is an important renewable system to consider. Biomass utilizes organic materials like wood, agricultural residues, and even municipal waste to generate energy. This process recycles waste into power, reducing landfill use and greenhouse gas emissions. Biomass energy systems are versatile, supporting electricity generation, heating, and biofuel production. They can be adapted to various scales, from small, community-led projects to larger industrial plants. Importantly, biomass is a reliable energy source, unaffected by weather conditions unlike solar or wind power. However, its sustainability depends on responsible sourcing and management of biomass resources.

Boiler dependent. Plus, the efficiency and sustainability depend on the supply chain for biomass materials. For individual buildings, biomass boilers can indeed provide heating and electricity. For communities, larger biomass power plants can convert waste materials into energy, supporting local energy needs while reducing waste.

The biomass is one of the last feed material to open another cycle in the Circular Economy, can be used in boliers fot steam generation, the enthalpy used to be transmitted to water is nearly the same that the fuel oil, with a big difference, the fuel oil is not enviromental friendly.

I agree that geothermal combined with heat pumps can offset heating and cooling costs in homes and buildings being constructed. Existing buildings moving to the technology seldom makes economic sense as the retrofit costs are much higher than when you can plan for the technology in a new building and have the undeveloped land around it.

Geothermal with a ground source heat pump is an excellent way to smooth out the highs and lows of temperature differences saving energy. The earth's temperature is a fairly consistent temperature around 55 to 60 degrees which the geothermal system captures. Using this technology is simple and straightforward with obvious adjustments to local geological conditions. The wells can be run vertically to depths typically to 400', can go even deeper or run horizontally, especially in areas with rock strata is closer to the surface.

GEOTHERMAL energy is available only at specific location and the trapping the energy is really difficult so we cant really depends upon GEOTHERMAL energy for large requirements

Focus needs to remain on reducing building energy usage and geothermal is a very efficient method to take care of building occupant comfort needs. You can retrofit just the main "powerhouse" equipment or the the individual room units depending on you budgets.

I disagree with the notion that existing buildings can't be retrofit with this type of system. We're in the process of retrofitting dozens of commercial properties to use ground source heat pumps (i.e., geothermal). Yes, they are cheaper to install during construction than in a retrofit situation, but that's true for virtually everything. Bear in mind that heat pumps give you cooling as part of the overall package, not just heating. If you're adding this capability to a building with no cooling or a small piecemeal current system, that boosts the financial case as well. It also allows you to run your HVAC with no scope 1 emissions, and minimal scope 2 if you purchase renewable energy.

As a first step , carry out energy energy efficiency project, to reduce your energy intensity and demand. In the case of electricity, energy efficiency interventions that result in demand reduction go along way in helping you size a plant matched in size with you efficient load. Secondly, In selecting the type of Renewable energy to deploy, you also have to identify what form of energy you are looking for e.g. if it is thermal energy then depending on available biomass resources. Then biomass maybe a viable option depending on the quantity of thermal energy you require. In addition, system controls such as building and process automation may come in handy in ensuring productive use of Renewable energy resources for maximum benefit. I

Demand side management is a cost effective and efficient option for energy management other than conventional solutions. The demand side management constitutes demand response and energy efficiency which are short and long term solutions respectively. The prior target alternation of energy within a few mins to day ahead, month ahead (TOU) or even instant shedding with direct load control. The former targets to enhance the energy efficiency of the overall system through more efficient appliances and other options.

A energia renovável é sem dúvida o melhor caminho para a jornada da descarboniza??o das empresas. Lembro que está atrelada diretamente a 3 grandes pilares: Eficiência energética, energia renovável e créditos de carbono, diretamente na sua ordem de importancia. Outro ponto extremamente importante também para uma gest?o inteligente de energia é a utiliza??o de um EMIS (Energy Management Information System). Com a ferramenta certa é possível integrar dados de diferentes fontes de energia e normalizar em uma gest?o de KPIs e Scorecards inteligentes. é a maneira mais fácil e rápida de garantir uma visibilidade em eventuais desvios.

It's difficult to supply a load with a single source of renewable energy. An integrated, portfolio approach is best, to source a combination of technologies more efficiently, minimising the use of storage and/or fossil fuels.

Building automation systems can enhance renewable energy conservation by optimizing energy usage. They regulate lighting, HVAC, and other systems, ensuring efficient operation based on real-time data. This minimizes energy waste, contributing to sustainability goals.
