What is P50, P52 & P90 ?

By
P52, P53 and P90 are terms often used in the renewable energy sector, particularly in the context of wind or solar energy production analysis. These refer to statistical probability levels used in energy yield assessments to estimate the expected production of renewable projects over a certain time frame. P50 : Represents the median or "best estimate" production scenario. It means there is a 50% chance that the actual energy production will be higher or lower than this value. It is the expected average production in a typical year. P52 or P53 : These are uncommon notations, but they might represent slight variations from the median estimate, with a slightly higher probability of occurrence than P50. P90 : This represents a conservative estimate, meaning there's a 90% chance that the actual production will be equal to or exceed this value, making it suitable for financial risk assessments. In summary, P-levels like P50, P52, or P90 provide different confidence levels for ...

Present scenario of Geo Thermal Potential in INDIA as on 2020

By
Image
The Lack of Proper Coal Allocation, Ineffective Reforms in the Renewable sector mainly solar, hydro and air is taking a huge toll on Indian power need, hence new sources of energy must be explored and is the need of the hour to fuel India’s need of clean energy. Geothermal energy shows promise for India’s future energy needs if developed properly, as it is an enormous, underused heat and power resource that emits little or no greenhouse gases, and is homegrown hence making us less dependent on foreign oil. Geothermal resources range from shallow ground to hot water and rock several miles below the Earth’s surface. A Mile deep well can be drilled into the underground reservoirs to tap steam and very hot water that can be brought to the surface for use in a variety of applications. Geothermal energy can be used very effectively in both on- and off-grid developments, and is especially useful in rural electrification schemes. Geothermal power plants operated in at least 24 countries in...

Concept on Self-sustainable 2W Vehicle

By
Renewconnect is working on the self-sustainable methods in developing a zero emission vehicle with the following methods and technologies. We are coming up with swapping of the technologies that can be integrated into the vehicle based on the fuel or the resource availability.  All the advancements of the vehicle will be updated.  Developing a self-sustainable two-wheeler is challenging but feasible with a combination of renewable energy, energy storage, and efficiency-enhancing technologies. Here are some key strategies for building a self-sustaining two-wheeler: 1. Electric Powertrain with Regenerative Braking Electric Motor: Use a high-efficiency electric motor to reduce energy consumption. Brushless DC motors (BLDC) are commonly preferred due to their efficiency and longevity. Regenerative Braking: Incorporate regenerative braking to recapture energy during braking, which can recharge the battery and extend the vehicle's range. 2. Renewable Energy Integration Solar Panel...

Calculating the carbon footprint of a country

By
The carbon footprint of a country represents the total greenhouse gas (GHG) emissions, primarily measured in carbon dioxide equivalents (CO₂e), produced directly and indirectly due to human activities. It includes emissions from energy production, transportation, industry, agriculture, and waste. Step-by-Step Process for Carbon Footprint Calculation Step 1: Define the Boundaries and Scope Before beginning the calculation, it is essential to define what will be included in the study. The carbon footprint is categorized into three scopes as per the Greenhouse Gas Protocol (GHG Protocol): Scope 1 (Direct Emissions): Emissions from sources that are directly owned or controlled by the country, including fossil fuel combustion in power plants, industries, and transportation. Scope 2 (Indirect Emissions): Emissions from purchased electricity, heat, or steam. Scope 3 (Other Indirect Emissions): Emissions from activities outside direct control, such as emissions from imported goods, internat...
