 PowerAPI is a middleware toolkit for building software-defined power meters.
 Software-defined power meters are configurable software libraries that can estimate the power consumption of software in real-time.
 PowerAPI supports the acquisition of raw metrics from a wide diversity of sensors (*eg.*, physical meters, processor interfaces, hardware counters, OS counters) and the delivery of power consumptions via different channels (including file system, network, web, graphical).
 As a middleware toolkit, PowerAPI offers the capability of assembling power meters *«à la carte»* to accommodate user requirements.

-## Use Cases
-PowerAPI is used in a variety of projects to address key challenges of GreenIT:
-* [SmartWatts](https://github.com/powerapi-ng/smartwatts-formula) is a self-adaptive power meter that can estimate the energy consumption of software containers in real-time.
-* [GenPack](https://hal.inria.fr/hal-01403486) provides a container scheduling strategy to minimize the energy footprint of cloud infrastructures.
-* [VirtualWatts](https://github.com/powerapi-ng/virtualwatts-formula) provides process-level power estimation of applications running in virtual machines.
-* [Web Energy Archive](http://webenergyarchive.com) ranks popular websites based on the energy footpring they imposes to browsers.
-* [Greenspector](https://greenspector.com) optimises the power consumption of software by identifying potential energy leaks in the source code.

-## Research Projects
-
-Currently, PowerAPI is used in two research projects:
-
-- [Distiller ANR Project](https://www.davidson.fr/blog/comment-reduire-limpact-environnemental-des-applications-cloud-davidson-consulting-inria-ovhcloud-orange-sassocient-pour-le-programme-de-recherche-distiller) that searches to reduce energy consumption of Cloud applications.
-- [Défi Pulse](https://www.inria.fr/fr/pulse-defi-qarnot-computing-ademe-calcul-intensif-hpc-environnement) studies how to valorize emissions from High Performance Computing (HPC) using as use case [Qarnot Computing's](https://qarnot.com/en) offers.
